If you are that concerned about the money then get a Canon 7. You won't really be missing out. I use my two Canon 7's more than my Leica M3, thought not as much as my Konica Hexar RF. If the Canon had an M mount it would sell for almost as much as a Leica. You can even buy brand new lenses for the Canon. Voigtlander just released a new 28mm in ltm. The Canon is a no brainer, and if you decide later to move to a Leica, you can use the same lenses on it as well.
Which 28mm LTM lens is that?
Really should stop praising the model 7, I might need another.
The m3/2 only has 50mm frame lines, so limited in focal lengths. Still plenty of nice 50mm lens available.
