You can certainly get a nice usable vintage Leica for $500 or less. However, you need to understand a few things before you choose one. Leitz made two different systems of 35mm rangefinder cameras.
The earlier system has a mount that accepts lenses that screw into the camera body (what we call 39mm screw mount, or LTM for Leica thread mount). They introduced this system in 1930 with the Leica I(C) model, and continued it well into the 1950′s up to the classic Leica IIIg. Concurrently during the 1950′s, Leitz introduced a new system that accepts lenses with a special bayonet mount (rather than screw in, the lens is placed against the mount lined up with a red dot and a quick quarter turn locks it in place).
