don't think they all work on the lower end bodies

check out the charts Nikon has for a D-40 & see if it will work with all your lenses

also a D-70

the D700x is due out soon & the bodies you mentioned will plummet in value

I agree re the that kit lens.

the VR zoom is a great all purpose lens - AF-S Zoom-NIkkor 18-200 ED DX VR
