I have a Rollei XF35. I've only put a few rolls in it since I bought it last year, but the results are fantastic. The rangefinder focusing is excellent for such a small compact RF. B&W fantastic results.
Also has some other nice features such as the self timer and flash settings (I use mine with a Rollei B flash).
I would say that the pictures that have been taken outdoors in nice light are superb. The indoor shots are good, very warm, but not as crisp as my Nikon SLRs with Nikkor lenses (I use FE2 or F301 with 24/2.8, 50/1.8, 105/2.5 and 35-200/3.5-4.5). But then you wouldn't expect them to be.
I bought mine for £45 (about 80USD). Flash was £10 (18USD) on ebay and neither have gone wrong.
The only downside of this camera:
1) the lens does not retract, therefore fairly big and sometimes I take my SLR anyway because I'm taking a bag.
2) no built in flash, which would be great for fill-in flash (normally what I would use it for when I am taking outdoor shots). If I am indoors, I would use the flashgun anyway.
As a result, I am thinking of buying a Leica CM or minilux but still not completely decided. Still going to keep hold of XF35 becuase I know that in summer when light is good outdoors, I'll get great results with a vintage camera that is fun to use.
