I use my Bronica SQ-Ai exclusively, and it's a fabulous camera. It's comfortable for me, and I've never had any problems with it. I bought it used -- seven years old -- for $900 for the body, 80mm lens, 220 back, waist-level viewfinder, speedgrip, and a few extras. You can get them for less now on e-bay. I know Mamiyas are great cameras, but the lenses and repairs made it cost prohibitive for me. I seriously doubt most humans could tell the difference between a large Mamiya print vs. a large Bronica print.
