In the past he has been really interested in Lava Lamps, Newton's Cradle, and anything magnetic. It seems the knick-knacks that have generated the most interest were small and relatively inexpensive. For example, a small laser pointer keychain I bought him a couple of years ago still provides tons of entertainment. Yesterday I showed him ThinkGeek and he really liked the Levitron. I wanted to ask the Slashdot crowd what were some other really neat, interesting gadgets? Is there anything cool in the under-$50 range that you would like in your stocking this year?"

I can't get circuits right the first time, even when I'm being paid to build them. That's what breadboards are for. You build it on the breadboard, go "huh, that's not right," fix it, and then transfer it to soldered perf board. You don't build with solder the first time. If you need it right the first time (because you're fabbing a PCB, for example) then there's hours worth of design review and double checking involved.
If you're worried about letting the magic smoke out... well, you can do that just as easily on a breadboard or spring terminals. Besides, being overly paranoid about the magic smoke is bad for learning. Go buy 100 transistors from digikey ($6 for 2N3904 / 2N3906), a dozen op amps, a couple hundred assorted resistors, etc. Obviously you don't want to teach carelessness, but paranoia about $0.05 components isn't warranted either.

Have you looked at a cold soldering iron?

Might be just the thing for child. ThinkGeek stocks them.

Bought it because it had a breadboard with basic power inputs so I could use it on other prototypes and easy to assemble external pieces like switches. Been using it again recently to build schematics I find off of various sites online. They have more basic kits that have snap in components. Don't know about these kids, but I would have loved one of those at 13 since I was already soldering and wire wrapping basic circuits.

dealing with sights and optics taught me about angles in degrees and minutes-of-angle and how they work with customay measurements and created triangles of horizontal trajectories. (there's mils for the same thing in metric).
dealing with virticle trajectory taught me about objects falling toward the center of the earth at 1/2 gravity x (time squared) no matter how fast they are going. and how quadrant is measured to compensate for various co-efficient's of drag and velocities/grains of bullets.
plus all the responsibility, maintenance, cleaning, and stuff. it was probably the best thing I got at 13. it sparked my interest in science and showed me how physics and math is integral in EVERYTHING you do.

You can often find used Fischer Technik kits on ebay, some of them 30 years old, for sale at a good price. Even at 30, if they are not abused they are quite usable. (I know, because I bought some and use them.) Unlike some other building sets, there is no shortage of replacement or add-on parts.
There are sets that go from basic building, like bridges and little toy push cars, to electric motors and pneumatic controls (compressor, air tank, air pistons, etc.!), R/C vehicles, and all the way up to computer control with feedback. The main direct-buy sites in the U.S. are: http://www.fischertechnik.com/ [fischertechnik.com] and http://www.studica.com/Fischertechnik/ [studica.com] but don't forget to look on eBay.

When I was a kid I enjoyed the Radio Shack electronics kits. I have not seen them recently, but they can be built rather easily with a piece of thin plywood and a bunch of nuts and bolts, plus the actual electronics which can be culled from scrap equipment. There are ample schematics on the web for building anything from simple radios to logic gates to metal detectors. Once they've been prototyped on the kit they can be built for a few dollars worth.
If you want to go the programming route, there are a few cheap boards out there. They're not very powerful, but good enough to run Linux, serve web pages, control lights, etc.. At 13 he's old enough to learn programming too :D

Those electronics kits from Radio Shack and other places with the resistors, diodes, etc and little springs and wires to use for breadboarding are pretty cool and educational. If he actually digs into those, it's pretty cheap to buy a real breadboard and a power supply and a bunch of real components and he can start making real stuff. If he graduates beyond the lessons in the book that comes with the electronics kit, pick him up a copy of Horowitz and Hill's The Art of Electronics [amazon.com], and let him get started with real stuff.
I think they're over your price range, but Lego Mindstorms are great.
You can always get him started with elementary computer programming. If "real" languages seem too challenging, HyperCard is great for starting programming, especially since pretty soon you start to find stuff you want to do but can't, and then find out that HyperTalk is a real programming language that you can start adding in piecemeal to your project, gradually learning programming.
If there are local scout troops, building and racing Pinewood Derby cars can be great if you get serious about going for either style or speed.
A basic model rocketry kit can be fun. It's cool to see it launch.

At age 13, the kid is starting to get old enough to do more than just play with gizmos - maybe it's time to start making them? I was building radio-shack springboard circuits when I was younger than that. Maybe an Arduino board would be appropriate - nobody has to know how to program to use it because there are lots of projects online, but it's a great way to get started tinkering with a hands-on implementation of code! I have a boarduino from Lady Ada. It's only about $25, that should leave you some extra $$ to spend on a breadboard, wire and maybe some other parts.

I heard this great story from a friend of mine; his grandfather sent him a tool box filled with broken clocks. That's it. Best gift ever!
As a kid, I had lots of internal drive; I was into model rockets and building my own toys and even a full-size R2 robot. But the basic foundation which allowed this was my Dad having introduced me to do-it-yourselfmanship. Give your son tools. Heck, set up a work shop in the house, and build things yourself; kids emulate, and plus you'll have fun. My father would re-model rooms and build walls and decks and all kinds of cool stuff. He was really good at it, too, and he'd explain what he was doing while doing it if I asked.
Pre-packaged science toys are neat, and I went through a few of them, but they also stream-line a kid's awareness; make them think that knowledge comes in shrink-wrapped, consumer packaging. Pre-packaged reality is for the sheep, and it teaches a subtle lesson in dependence on the system rather than giving them the confidence to work, literally, outside the box in the real world.
One of the ways my father got my mind ticking was when I started pining for a pinball machine, clearly well beyond my pocket allowance budget. My dad said, "Well, heck. Let's build one."
So we did. And it was lame. --My Dad thought pinball was about trying to launch marbles into little holes. We did build a cool wooden table which was the right shape using a jig-saw, and he came up with a neat spring-loaded plunger, but I wanted electronic bumpers and blinking lights and such. So on my own steam, I visited electronic parts stores in search of various bits and pieces to create my vision. I learned about basic electronics and how to rectify AC current by bugging the shop owners with lots of newbie questions, etc. It led to a half-assed pinball machine, but it was still pretty cool for my age, and I learned a ton. --But none of that would have been possible if my Dad hadn't taught me how to use a soldering iron and power tools. He had given me the confidence to know that humans are smart and that with an inventive mind, you can do almost anything.
If I were you, I'd take your son to public science fairs and rocketry clubs and robotics clubs and whatnot. Stuff to fire the imagination. Also be sure to introduce him to the wonderful world of surplus electronic parts stores.
But above all. . .
Tools.
Buy tools and show him how they work, how to respect them. Build a decent work bench. Set it up with a good, solid vice. Lead by example. Build some awesome projects around the house, and make getting the tools a part of the game. In short, be an empowered geek. While pre-packaged stuff is fine sometimes, never let it dominate. Don't let other people do it for you if you can avoid it, because building stuff yourself is half the fun. This attitude will help your son in life in ways you can't even imagine!
