I own a Canon 30D and am very happy with it. If you have already read most of the reviews at the other forums, I doubt that I could add anything new. I don't think you'll go wrong with either one.
The main reason I went with the Canon is that there seem to be more lenses available for it. You will probably spend a lot more money on the lenses than the camera and the camera will probably be replaced at some point. Of course, you will need to replace it with one that will allow you to use the lenses that you already own.
