I don't get much of a spending limit for xmas, but I would like to start out with a dslr. I already have a Nikon N65 35mm slr and some lenses so I somewhat know what I'm doing. I know everyone dislikes the nikon d40 and d40x, but it is pretty much all I can afford. I have two lenses which I'm sure of which won't autofocus but will still work in manual. Should I just go for the d40 or d40x, or should I buy a used d70 from keh? Thanks.
