I guess the trick is to clearly explain the work that's been done on your web site without offending the manufacturer. The ideal would be to have
a mouseover or clickable link from the word recertified and the visual that says something to the effect of: "All Adorama "Certified" cameras and equipment have been tested and brought up to spec by the manufacturer."


If you aren't mentioning Canon by name they may not mind. If the explanation of what's been done to the equipment gets too vague and generic, you will lose trust and sales.
