In reading all these posts I am surprised that no one suggested that one might also want to consider a used pro digital SLR. I'm "stuck" with a bunch of older Nikkor prime lenses, so logic dictates that I should stay with Nikon. As an upgrade to my D1 I would look at a used D1X before I would consider, say, a new D100 kit at roughly the same money. I should think the same logic would apply to Canon gear. Spent a day last week taking some promo shots of a recording studio, and having used my D1 in the same room I felt that it would have stood up reasonably well to the 20D with an adapted 21mm Leitz lens we were using, at least for the kind of staged, long exposure low ISO hot lit shots we were taking. All this said, if I didn't have a bunch of Nikkor lenses and I was going to go out and start fresh, I would sure consider the Canon DSLR offerings as well. The 20D is quite impressive.
