Ditto - my camera varied between less than satisfactory to totally frustrating, from new until I sent it away after trying everything and with all sorts of lenses. Parts had to be replaced and it took ages, but the repair has made all the difference - it is now as accurate as my D200! So at last it's a good camera. No focus fine tuning required so far for any lens (10-300mm), DX or FX size.
I would encourage any reasonably careful experienced photographer who is not getting reliable obviously sharp shots from the D7000 to stop testing and soul searching, and immediately send it in for repair while still in warranty.
