Nobody has yet mentioned the Hapo 66e. Mine was 15 bucks, has a great Enna lens (75mm f/4.5, but some came with f/3.5 models), uncoupled rangefinder, and a somewhat counterintuitive but very handy auto film advance. It worked great out of the ePay box, still does, and is my MF carry-around of choice. They are still cheap, and the sister camera the Balda Baldix (or is it the mess-Baldix?) is not quite as cheap but still affordable.
