Background: I grew up using Canon SLRs (slowly going to digital when I purchased my first XSi about five years ago, now owning a 5D M2 and a good amount of glass) and love using them, but I'm intrigued by the rangefinder cameras of old (and today!). I tend to do a lot of photography out on the street and of people.

What's a good set of gear to get or borrow to see if I enjoy rangefinder photography? Is it worth to get an old Russian leica 'copy' or something similar? It's a whole new world for me, and searching online just seems to result in 'Get a Leica!'.
