My Nikon n8008s has all the important stuff. Big viewfinder that lets me see the whole frame even w/ my glasses on, takes cheapo AA batteries, has a spot meter, 1/8000 top shutter speed, AE and AE Lock, all that and more......for $40. Unlike another poster here, I gave up on the Leica R bodies. My R3/4/5 cameras were sorta crappy w/ shutter lag issues, and that R3 weighed a ton. Dark viewfinder too.
A Leicaflex is so much better than any of the R bodies (best viewfinder of any camera ever made), but my favorite Leica R camera is the Nikon n8008s w/ an adapter to shoot my Leicaflex 90 lens.
