I am an happy owner of a Bessa R: it's cheap, affordable, well built, with a beautiful and clear finder. It also felt two times in the concrete with no problems (the plastic top and bottom covers can damp the shocks more than an all metal body): I think it's the right choice to enter in the rangefinder world, you can buy them new with warranty and they don't use obsolete mercury batteries.
Also, i cannot understand why to buy a screw mount Leica (oh, yes, it's a Leica), when there are much more beautiful (yes!) and cheap Kievs out there:
Compared to a screwmount Leica a Kiev is a much more modern machine: it has a huge rangefinder base (a joy to use), metal shutter, prismatic rangefinder mechanism, one single ring to select all the speeds,
combined rangefinder and viewfinder, faster speeds, and you can buy from Fedka or an other good seller a "clad" camera with a real "return warranty" for less money than a "no-warranty" old Leica.
And about the lens: my Jupiter-8 and my Heliar 103 are both better then my Summitar: don't forget that the Jupiter where Zeiss copies...
