Keith-C: you are, in my opinion, might be a little too pessimistic.
Measured by todays standards: in my opinion and experience allmost EVERY brand, including top consumer bands, shows defects in some degree. The more you know of a specific brand the more you also know of those that should not have left the production. Even a USD 20.000 Patak Philippe has small mistakes which they claim their watches does not have.
This forum is a place for those with problems, interest and knowledge, like yourself, so in this line this thread is balancing.

By the way my 7D had a transport damage, but that is not to blame the camera.
