I love my Rebel XT, it takes fabulous pictures and is more than enough camera for my purpose. It's only down fall is the plastic body. It feels light, seems fragile and almost seems like a toy. I played withe a Canon 30D and a Nikon D70 and was very impressed with build material and quality. But the price was way over my budget.
In my opinion you can't go wrong with a Rebel XT or a Nikon D70. Either camera paired with a nice pair of lens good technique, compostion and even some post processing adjustments will yield timeless photos.
