Hi all, I'm new.
I just stepped up to a d90 from a d40 (good choice on my part). My dad has a d200 and seemed to do a thorough job comparing them...I don't think there's a whole lot on the 200 that the 90 doesn't have, not to mention the upgrades in overall technology, lighter weight, etc... I do believe it has the same metal interior...read it somewhere.
