>>3196624modern lenses are better, but for ordinary 35mm film it's irrelevant, just pick whatever you'll enjoy using. newer bodies may have more/electronic features, but they all take the same pictures.
if you have nikon G lenses, pick up one of the later autofocus bodies. if you have nikon lenses with aperture rings, pick basically any body since 1980.
there are lots of bargains, I like my FG and N90s.
