I had Canon SLR, now I jumped to Nikon D80, tought Canon Rebel XTI or 400D, comes with a not that god lens, it's very slow, to short and cheap plastic construction.
So, if you want better lens, the 17-85 IS, for example, you pay much more, but you still have shorter lens then the new Nikon 18-135mm.
The grip on Rebel, it's a nightmare, to small, if you to take a lot of pictures, you'll get very tired to hold this camera.
I love my new D80, the pictures are just great, the lens, I love it, it covers from 27-202mm on SLR and it is fast and good quality, the camera, no words, it is a great camera with the famous great construction from Nikon.
Take a look on this link, Nikon D80 vs Canon :
http://reviews.cnet.com/4520-11396_7-6654246-1.html The D80 had won all the way, got 45 point out of 50 and Canon 37.
My suggestion, go for Nikon D80, you already some lens, don't lose your investment, you can use those lens, and if you have some extra to spend, get the 18-200mm VR from Nikon, that is the Mercedes of lenses right now. You might have some problems to get one, everybody wants one, so it is out of stock, but if you can get, do it, it will be much better then D200 with another lenses, but if have a lot to spend, then get the D200 with the 18-200 VR (there is a regular 18-200, don't take that).
God bells you.
