I used to use a Bronica SQ-A for a number of years, the Zenzanon 80mm f/2.8 PS lens was sharper at f/2.8 than the Carl Zeiss Planar 80mm f/2.8 - at f/5.6 it was a real toss up as to which was sharper. I used the chemmeney metered viewfinder with my SQ-A and I just loved that, a big bright viewfinder - the lateral inversion of the image didn't bother me because I already shoot large format. The Bronica SQ-A also worked quite well with the ultra-bright replacement minolta screen I flogged from my hasselblad CM.
One thing to watch for is that the backs do have a tendency to develop light leaks in them so run a test film through the camera and be sure to watch for that - also getting a second back for colour film is Highly reccomended!. With thicker films like Kodak T-Max 100 and Fuji Neopan sometimes you need the pressure plate in the back to be adjusted so the film is smashed flat against the film rails, you can tell if your camera needs to have this done if the negatives seem slightly out of focus around the edges, this is because the film is buckling. You also have to watch out for excessive force being needed to wind the next frame on the camera, because the lens leaf shutter is cocked at the same time as the film is wound on if you feel excessive resistance as you wild the film on it can be a sign that the leaf shutter mechanism is getting old and may fail.
