Does it have to be Nikon? You can pick up a manual-everything Minolta set-up from (Minolta X700 and 50mm f/1.4) for $100 in Bargain condition (which has always been closer to mint than bargain for me), go up to ~$225 total and you can also get a wide angle and a telephoto.

The X700 gives you the option of full auto-exposure, aperture priority, or full manual everything. Why does it have to be a new camera? Go back a generation to the manual focus cameras from any of the companies (Nikon, Canon, Pentax, Minolta) and you'll find what you are looking for.
