A 1.0 finder basically has no magnification, so it means you can shoot with the other eye open, some people like that. Personally, I'm not bothered although I did try the R3A in a shop and the finder is lovely, every bit as good as a Zeiss Ikon if you ask me, which is kind of considered to be about as good as range finder finders get.
The R3M + lens looks like a nice kit, you could do a great deal worse than that.
Although people talk about the wonderful build of Leica, which is course true, if you're used to modern DSLRs and compacts, then the build of the Bessas is just as striking.
A Bessa is a great camera, not just a starter model, but you could shoot it for the rest of your life and not be disappointed I think.
