The older fellow that works there (I think he might be the owner, Peter) is very knowlegdeable of everything camera-related. We have brought him 2 SLRs for complete overhauls. It was about $100 each and they had them for less than a week. My camera works great now and I wouldn't trust anyone else to handle any of my cameras in the future!
They also sell equipement and their prices seem pretty reasonable, althoughI've only bought a tripod from them.. .so far.
