It was refurbished, and I believe thats why it only lasted 2-3 years.
Actually it was probably not the case of being a refurb. My 60D for instance came through with about 45 actuations and most reports by people indicate that a very high percentage of refurbs are probably a couple hundred or less. I really have seen only one "bad" report of a refurb in that a user reported a scratched unit, well worn, with something like 10,000 actuations. As I recall everyone said return it and when he did Canon was quite apolegetic. Don't forget with the refurb you have a 14 day exchange and a 90-day warranty. I'd save the money, get a refurb, check the shutter actuations and if excessive request a different unit.
