Hmmmm, loads of good info here, to which I can't take exception...errr, well, except for one thing: I can't at all recommend, if you can afford a decent camera, buying a Soviet camera. I've handled a few, and while it's possible to make good photos with one, doing so can be very, very challenging, depending on your camera/lens/both. That's partially because, unlike with Leica, Minolta, and several of the other better quality cameras mentioned here, Soviet cameras and lenses tend to have quite a lot of variation--in areas where, really, by design they weren't supposed to. The results vs. effort ratio with those things can be very low indeed.
The only Soviet camera I ever owned--I've still got it, in some box somewhere--is a Zorki 4K. I did my research before I bought it on eBay, and picked that model and specimen because of the large viewfinder with diopter adjustment, the fact it was a later-model camera and so theoretically more "advanced," had a decent reputation compared to other Soviet rangefinders, was in very good condition, and came with a Jupiter-8 lens.
The lens was not bad--I actually used it for a while with an LTM-M adapter when I finally acquired an M3--but again, not very nice ergonomically. The aperture ring has no click stops, so it's easy to move it accidentally during shooting, the F-stops aren't equally spaced on it, it *feels* cheap (aluminum barrel), etc. The camera? Yeesh.
It did look in very good condition on arrival. And I managed to make a few photos with it--I think, I never did get to see them. But then the mechanism inside seemed to just sort of fall apart, and the rewind didn't work when I tried to at least salvage the roll of film. Even if the camera *had* worked, it was not anything like a Leica, or other even ergonomically friendlier camera. To load film, it wasn't just the bottom that came off the camera--both the bottom and the back (as a single unit), come off. While it did have diopter adjustment, the adjustment lever moved far too easily so you'd have to continually readjust it. The shutter speed dial was finicky--if I recall correctly, you'd *better* not try to change the shutter speed before cocking it. And it felt egregiously heavy--not in the Leica way, where the cameras do tend to be heavy, but that's because they're full of finely engineered, high quality, (nearly) all-metal parts. The Zorki felt like it was heavy just because no one had bothered to refine the thing to the point that it made as efficient use as possible of the metal in it.
To me, a camera is like a musical instrument--you want to be able to pick it up and just play it, and you don't want anything to interfere with you getting your groove on with it. (I've heard guitarists describe certain instruments as sounding sweet, but being a b***h to play. Generally, they prefer to use a guitar that has both a sweet sound and is at least relatively easy to play.) You can get some sweet images, sometimes, from Soviet cameras--but many of them are not at all fun to play, and just the effort and discomfort involved with trying to get them to play properly is frustrating and counterproductive to making nice images.
Sorry, I don't mean to offend anyone. And, errr, yeah, they *are* cheap, so there is that. But let me be blunt: I have yet to see or handle a Soviet rangefinder that wasn't basically relative crap next to loads of various fixed-lens rangefinders. Let alone quality interchangeable lens cameras from most non-Soviet manufacturers mentioned here.
Personally, if I was to vote: get the Minolta CLE. They've got their oddities--no metering in manual mode probably being the chief one. But then, if you're shooting with a rangefinder, do you *need* metering anyway unless you're shooting transparency film, isn't everyone using Sunny 16 and capable of just looking at the lighting and getting within a half stop of correct exposure without a meter? Or do folks not do that nowadays? (Personally, while I carry a meter, I generally don't bother with it--I've gotten pretty good at metering with my eyes and brain.) But Minolta makes very nice gear, if you're using autoexposure and your meter works the CLE has an excellent metering system, apparently they are repairable at some places still (I've heard, but can't swear, that some of the electronic bits/PCBs were shared with Minolta's SLRs, and most electronic problems with them are actually dirty contacts/cracked solder joints that are easy repairs vs. circuit boards that do indeed fail entirely), and the 40mm M-Rokkor is a great lens--I once had one for my Leica Ms, and am still regretting that I traded it in on a 35 Summicron Version 2.
