So this year I'm taking a photography course at my school. Obviously many press photographers have long moved to digital cameras because of their flexibility, but both for the purpose of the course, and my personal preference, I picked up a Used Nikon F2 body over here for a good price. I don't recommend buying anything on eBay, as the one I bought had problems.
Why a Nikon? Because the lenses are backward and forward compatible for the most part. With exceptions, manual and auto-focus lenses can be used on both manual and auto focus bodies -- even digital. Whereas Canon changed lens mounts like a philanderer on a quest for the prettiest mount that day, Nikon faithfully engineering in backward compatibility. The F2 is a beautiful, totally-mechanical camera. Lots of juicy information on the Nikon F2 Body here at the bottom of the page.
