I had to have some repairs done on my 60D due to circumstances beyond my control. Last summer the camera and 3 lenses were stolen by a local guy here. Not sure why because there really isn't anyway to get rid of them, and although it took the police more than a month to finally catch him, the end result was inevitable. Then they had to keep the camera and the one lens they recovered (100mm L IS macro) as evidence for several months until the local legal system ground out its slow route. I finally got the camera back in January, then found that the top dial no longer worked. Everything else seemed to function fine, but I couldn't change any settings without using the Q button and navigating on the back screen, which is rather clumsy when you are used to having both dials. Couldn't really use manual at all.
It is also a bit difficult to send it to a repair facility while living here in the Bahamas - FedEx shipping is the only option and it's prohibitively expensive. I ended up having to send it home with my wife's sister after she visited last month, have her send it in to Canon, then when she got it back, send it to my sister who is coming for a visit in April. What it amounts to is that I had the use of a damaged body for about one month out of the last 9.
I am very happy with the responsiveness, and the ease of actually working with Canon. Filling out the repair ticket online was a snap, their response was fast, and my sister has checked out the fully repaired, warranty covered body and has it ready to bring back next month.
