If you dig, there are probably multiple threads on the forum about this very question. Really, outside of a hasselblad or similar expensive setup, output is pretty similar for most 6x6 cameras. Really comes down to what onei is willing to spend, and what is most comfortable to use. A good working Yashica will work fine. I love my Bronica...if looking at them, get and S2 or S2A. Plus you can swap lenses. If that isn't a concern, there are plenty of TLRs that basically do the same thing, with different levels of control. I've never used the Mamiya TLR but I've heard good things. It's heavy, so portablility is another factor. When i was in Japan, I actually bought a Yashica because I liked it, and The Bronica was very heavy and cumbersome to carry around, particularly when carrying other cameras at the same time. Most TLRs are light and easy to work with all day long.
