I am comparing the Canon 400D, Nikon D80 and D200 which is better in your opinion and why? I am looking for a mid-pro range with an 18-200 lens to keep for several years.

My first choice was the D80 and then Canon annouced the 400D few days back. which 18-200 lens with vibration reduction would be a good choice with that model? would you get the 400D over the Nikon D200 if you had the choice?

Any help from first hand experience is appreciated.
