Unless you really just want to have a Leica, for the sake of owning a Leica (which I will eventually succumb to), why not get the R2C?
And, just to put a Leica into perspective, you should try to fondle a Mamiya 6. It has a palatial viewfinder, with a very bright RF patch and with the vast acreage of a 6x6 frame, you can shoot fast film with boulder sized grain and still get detailed prints (shoot Kodak C35 B&W film pushed to ISO1200 and get huge, grainless prints from it). You get a TTL meter and aperture priority in the mix as well. All for something comparable to a Leica M3 w/CLA and a decent Summicron to go with it.
AND, one more option is to bide your time and get a Kiev 5 and have it CLA'd. The VF on the Kiev 5 is big and very bright. Maybe not as bright as my old Bessa R2, but certainly in the upper ranks of VF's. You get to use all your external mount Contax lenses (sadly, none of the wonderful internal mount 50s will work).
