Buy a Leica copy from APUG and a Soviet lens. It will cost around 200 but what a camera ! I used original Barracks and the good Soviet ones mechanism and winding knobs , focus works velvetly smooth.
Buy a real camera not japanese tourist cameras.
What's a "Leica copy?" APUG sells cameras, or do you mean from the classifieds? I couldn't find anything on Barracks, is that a camera?
