Here are a couple of links with good information:

So far, I have found rangefinders come in 2 styles: big and beautiful, or small and fiddly.
If you wear glasses, have big hands, or like the feel of a big solid camera, these are for you (in your price range). They are usually very reliable, most are fully mechanical, and they all have excellent lenses.
Konica Auto S/S2, Yashica Lynx, Yashica Electro35(no manual), Olympus 35SP(most expensive), Canon QL17 (early version with 45mm lens), Minolta Hi-Matic.
If you have small hands, good eyes, like the idea of a compact camera, dont mind compromising on some things, these are for you:
Canon QL17 Giii, Yashica 35CC(no manual), Olympus 35RC (smallest), Olympus 35RD, Minolta Hi-matic 7Sii (most expensive, Minolta Hi-Matic E (no manual), Konica S3 (no manual)
Of these I usually recommend the Canon QL17 Giii. It has full manual, is compact but has a nice bright viewfinder, canon made over a million of them, so they are easy to find.
It is has a really nice fit and finish, giving it a very luxurious feel.
*keep in mind that any vintage camera will likely (50%?) have issues.
The foam seals around the film door will need to be replaced. You can buy kits and do it yourself easily enough.
Slow speeds are 90% likely to be slower than labeled. As you are unlikely to shoot at .25 or slower, this is mostly irrelevent.
Make sure the seller will allow returns.
As soon as you receive the camera, test it fully. Make sure the shutter is quick does not have oil on it. Inspect the lens inside and out with a flashlight. Have a battery ready before the camera arrives. Point the camera at grass or other medium-dark surface at noon and the meter should read about f/16, 1/100s, at ISO 100. Check the rangefinder, make sure at infinity the lens and rangefinder agree. When focussing closer, the rangefinder patch should move immediately and have no 'delay'
Put a roll of film through it asap.
