I've purchased both new and used from Adorama, and have been very satisfied. I had an issue with a used part that might or might not have been with the part itself, it might have been something in the camera I was using it on; Adorama offered to accept the part as a return and they refunded my full price. My sales contact, Frank, is a good guy, funny and friendly in a brusque New York salesperson kind of way; direct, but trustworthy. I took his recommendation when ordering a used film body, and it has turned out to be my favorite camera, a Canon F1N. GREAT camera. And great service.
