The SQ-A is my "most serious" camera for film based "art photography." I like it. I had a problem early on with bad indexing in a back, although that showed up immediately and I returned it. I also had some mysterious jam of shutter linkage in a body, corrected by replacing the body for -- like -- $90. The back/magazine is known for plastic foam light seals getting goopy with age, but that is fixable as a DYI project. I've had mine for nearly six years now and quite like it.
