you should look into the Tokina AT-X 165 PRO DX, its a 16-50mm f/2.8 and its WAY cheaper then nikons 17-55mm (half the price)
i visited the Tokina booth at the CES and talked to one of the reps, all there new lens will included a built-in motor though you wont
have to worry about it.

waiting for an update
