see if you can get a Fuji S5Pro + Nikkor 17~55 f/2.8. Add a SB800/900 (not sure if 900 works on the Fuji.
Its is Damn accurate for skin and white gown. The Bride will love you long time.
Simple yet.. not so 'advance camera' .. built better than the D90, less complicated than D300. All time wedding/ landscape/ portrait camera. :-}
