And buy new. A camera's shutter does only have a certain number of actuations in it before it stops working, so better to start at 0 rather than 10,000 or whatever a used camera's shutter count would be.
most are rated at like 75k +.

its also not hard to check. and if you are buying used, sure be cautious, but you can usually tell which have been taken care of and which have not.
