I finally made the plunge and ordered the D700 together with a SB-900 yesterday!!! (It was a package deal) Picked it up from the shop today :-D The first impression when i picked it up was the feel of quality... the i put in a charged battery and looked through the viewfinder... wow thats much bigger and brighter than the D200! The manual is quite thick.
Have been taking a few test shots and fiddling around in the menu so far..
Thank you all for your kind comments! It's definitly a big step forward from the D200 (even if it stll a good camera except for high-ISO performance). The build quality is every bit as good as i expected. So far i'm a happy camper
