Also late to the party here: Overall I have had a good experience buying refurb gear from Canon. Only issue was purchasing the Canon 7D a few years back. The in-focus rate was horrible (less than 25%) even after calibrating my lenses and tweaking my settings. I sold it a year later when I got my 6D. I ended up picked up a used 7D last summer and the in-focus rate is nearly perfect on the same lenses.
