That was one line of thinking, dad's camera was 2 stroke, and if I were to get another M3 it would be a single stroke. What I love about the older leicas is they are not battery dependant which sort of scares me a bit with the VC Bessa R2a, I had my Canon AE1 crap out on me when the battery died. In the end I can find an M3 here in the GTA for about $1000 Cdn. So it looks like I answered my question.
