lets get to the point, i'm looking at purchasing either a used 1d or a used 1dmk2n. i dont have the funds to get either of them new, and im really looking for the fast shutter speed, so buyihng a new 20d for instance would not be an option. other than the megapixles, what would be the advantage of the mk2N? also, the mk2N would cost me about a grand extra so with that money i could get some glass....im stuck. anh help is appriciated. thanks.
