I’m shopping for a Canon 5D Mark III body, and I found a store on ebay with a 99.6% positive feedback rating and with great pricing; it was originally part of a kit and they are selling the body and lens separately. My main concern is they are not a factory authorized dealer. While I can save a few hundred dollars, I am worried able warranty & service support after the sale. My lean is to buy from one of the three companies that Bryan Recommends. I’d appreciate your feedback.
