Recently I sold one of my D300 bodys and replaced it with a D4 - probably the Best Nikon Digital Camera Ever.  I kept the D300s to take advantage of the DX lenses I have and for it's "crop" capability.   I have seven  lenses for these cameras: a 10.5mm f/2.8 fisheye, a 12-24mm f/4.5, an24-70mm f/2.8, a 70-200mm f/2.8, an 80-400mm f/4.5 VR & a 105mm f/2.8 macro.  I also use a Nikon P7000 for fooling around and  because it's small and light and usually in my pocket.
