I have a Contessa and it's an excellent camera! It's Tessar is one of he sharpest lenses I've ever used.
Have you looked at getting a Contaflex instead? It's uses a similar, if not the same, Tessar lens. It's an SLR, so you wouldn't have to fiddle with RF focusing and it has a bigger viewfinder. They come up for sale a lot more frequently, too.
