If you want to try an FSU option I would strongly recommend you just sent me all the money you have to spend and I will send you a rock.
Not to minimize your angst, but that may be just a bit harsh. While I don't question your poor FSU luck, others may have had a bit better fortune.
I purchased a Fed 3 from a fellow APUG member a while back just to see what was up with these FSU cameras. It has subsequently functioned very well with nary a single service issue. Took climbing a learning curve on my part as it does NOT normally operate in the "standard" ways to which we have become accustomed with mainstream cameras.
Although I don't know the camera's provenance, I do know that the shutter timings on this thing are closer to perfect across its range than any of the other cameras I own, with the exception of my large format Copals. I know this because I measured them with a shutter tester after assuming they'd be hideous. They weren't.
And just to add insult to injury, the camera also has the clearest and easiest-to-focus rangefinder mechanism I own. Better even than my Canonet QL17 G-III. And there's an excellent built-in diopter correction that will shred your flesh using it, but which works wonderfully well. The Canonet lacks this feature entirely.
All one needs to do is get past the truly wretched fit and finish, and the horrible feel and sounds that emanate every time one winds a new frame. You'd swear the thing was about to fall apart in your hands.
The negatives, however, are uniformly excellent.
Who knew?

[Edit] In fairness, I just remembered and forgot to mention that the camera's rubberized cloth shutter curtain did have two areas of pinholes when I received it. I temporarily "fixed" these by covering those areas on the back side with small squares of black photo tape. That added a little extra mass to the shutter system, but did not appreciably alter the shutter speeds. This MacGyver-style fix seemed highly appropriate for an FSU camera, and has worked so well that I've just left it as-is.
