I have a Rolleiflex and I love it dearly. I used to have a Yashica, and as much as I liked the Yashica, it didn't handle nearly as well as the Rollei. As far as sharpness goes, I'm sure you can measure that the Yashinon lenses are every bit as good as the Zeiss Tessars, but tell you what, the prints from the Zeiss looks better to my eye. I can't put my finger on it, there's just something right about them.
With that said, both are good cameras. I think it's a matter of taste. TLRs are fun to work with, and I believe that in the hands of a good photographer, the difference will not be noteworthy.

Thanks for the input. For $50, I would have worn it for a hat. For now, I'll stick with Roger's advice. There are only so many hours in a day, (and never enough in a night, but that's another story) and I do have plenty of gear to work with.
