There's a lot of good advice here. When you do end up buying another camera, be sure to handle the cameras, if at all possible. That will also assist you in making a decision. Don't buy simply on price or brand name.
The Bessa-R is really a sweet little camera. The Voigtlander lenses are excellent.
Long-term durability seems to be decent, despite the moderate use of plastic. The primary weakness of all of the Bessa rangefinder cameras is Bessa's apparent inability to properly calibrate the rangefinder. That's judging from the number of comments on various discussion boards that all point out this problem.
My own Bessa was fine. However, my Rollei 35 RF (Bessa-R2 clone) is out vertically.
