Two things to consider:
1. Buy a D200/300 class nikon body that will meter with manual focus lenses or switch to Canon, etc.
2. The Leitax adapter is the one to consider for F mount. There are no other equivalents.
(again, if you switch from Nikon to Canon, Pentax, etc., then you do not need this conversion and use adapters and get metring).
There is nothing special about Nikon, so, I would strongly suggest that you dump it and get a more versatile brand.
