I like the Bessas. I have an R not and R2, as I have L39 lenes and need a self timer, but M and L39 lenes can be used together on the R or R2 via adaptors. The new Zeiss Ikon should be worth a look when it goes on sale. It has a much longer rangefinder base, which should make longer lenes more usable and although it seems likely to be more expensive than the Bessas, it's still going to be way cheaper than a Leica (and you don't have to take it apart to put a film in like a Leica).

Like others, I too still have a soft spot for the Cannon GIII, although I no longer have one. You can't change the lens, but it would fit in a coat pocket and was all but totally silent.
