For your budget, you may get lucky and pick up one of the earlier Yashica TLRs such as the Yashica-12, a predecessor of the Yashica-124 and 124G, with the difference that the Y-12 doesn't take 220 rollfilm, just 120, which is fine. It's well made, and the Yashinon lens is a very good performer. The 124 and 124G models sell for anywhere from twice to three times your budget, but the 12 can be picked up for very little, yet optically there's no difference, and the build difference is slight.
For 35mm rangefinders, you're spoiled for choice, though you may need to factor in a CLA, which will of course break your budget. However, for sheer fun yet great reliability and pocketability, it's hard to beat the diminutive Olympus 35RC. It has a cult following, one could say, but for all the right photographic reasons. I also like the Yashica Minister range, and if you want to give up manual control for aperture priority auto, the Yashica 35 Electro series cameras have great, sharp, colourful lenses.
For sure, you'll need almost certainly to replace the light seals, but that's half an hour's easy work and around $10 with a light seal kit from Jon Goodman (there are others, but I've used Jon's kit and it's the business). One of these kits will do many cameras. He sells on eBay as 'interslice'.
Although it's not what you've asked for, you can have much fun with an old folder, and its capability will surprise most. For reliability and the best chance of bellows that are light tight, at low cost, look out for one of the economy Zeiss folders, like the Nettar or the Ikonta. You've a range of 6x4.5, 6x6, and 6x9 to choose from. Old bellows cameras are very pocketable, which is a great asset, and they make people smile when they see one in your hands, which is an even greater asset.
