Wide Angle - After lot's of research I ended up with Sigma 10-20mm. I know you have an aversion to Sigma, so the Tokina 12-24mm was next on my list. The Nikon lens is slightly better, but a lot more expnsive
Macro - Heard good reviews of Sigma 105mm macro ....ooops Sigma again
D200 - If I was sensible when I upgraded from D70, I should have gone the D80 route. Will produce same quality images as D200. Nikon D200 is just built for more abuse & has more manual controls to hand , which is of more use for pro's / semi pros. Problem is if you hold the D200, then you'll want it
HTH
