Barbra I think that the canon is excellent but for some people the Nikon is better,if you go to
www.dpreview I think there may be a comparison check
I bought the Nikon D70 because it had everything ,and filled my hands comfortably,the feel is quality,the spec on the canon is good but for me it has a cheap plasticky feel,the 20d at the time was much more expensive by a couple of hundred
