Ditto the kudos for United Camera. I've used them twice. Lower cost and faster service than Canon direct. Plus much greater ease in the transaction. You can actually talk to them, or they respond to e-mail quickly.
Only one complaint, which turned out to be a big benefit. Sent a Canon 5D2 body for repair of the CF card slot pins. Included instructions to do nothing else, specifically to not update firmware or try to clean the sensor. They didn't touch the firmware, but they did clean the sensor and noted that on the return invoice.
I was fearful some gorilla had swabbed it with Q-tips and Windex. But when I did a check image, the sensor was cleaner than I had ever seen on 4 cameras I've had.
My CF card slot pin replacement was $100, about half the price from Canon. And no extra charge for the sensor cleaning.
