We have the Rebel XS dslr .. It is an amazing camera for being an "entry level" dslr. You can take some amazing pictures right out of the box and it is pretty easy to use right from the start. There are a lot of advanced features on it that will take some time and patience to learn, but that is ok.
The addition of a zoom lens adds about $350 or so to the cost so be prepared for that. We just got our lens shortly before our vacation in August. My wife finds that she uses it far more than the standard lens that comes standard with the camera.
A good idea with whichever one you do decide on is to check with your local camera shop. Some will offer a classes on using the camera. Well worth the time.
