Don't worry about FSU normal lenses. Alignment problems are a problem with very fast lenses, if at all. You don't have money to burn anyway, get a Jupiter-8 or an Industar-61, they will fit.
As much as I like FSU bodies, if it's your first rangefinder I'd get a Bessa R. Having a nice modern mechanical body with metering is a nice thing, and the viewfinder runs rings around the other options.
Bing! You're hypnotized!
