Rebel XT seems to be the right one for the $1,000 budget. Otherwise, Canon 20D is a better choice to spend over $1,500. These 2 camera are eqipped with Canon Digic II processor and new CMOS sensors. The quality of picture shooting by both cameras is outstanding. I'd say much lower noise than Nikon D70. Any way, test them yourselves under the dimmer light condition. Good luck.
I'm very interested in learning photography and would prefer to start with digital. what DSLR can you recommend for a beginner, something affordable yet has the right features?
