I'm thinking of investing in a Leica rangefinder and adding to a few already owned lenses.
I already own a Bessa R which is a joy to use, so I'm no stranger to Rangefinder usage.

Problem i have is which one to go for.

Ive narrowed it down to a IIIc/f for size/handling. An M2 as a Leica entry into a similar camera i own, or i could stretch a bit more for a M5 which i have always liked the layout and controls of.

I'm actually not looking for a camera to put on the shelf, I want to use it, so what are, if any problems should i look out for apart from speed's, holey shutters etc...?
