If I were you I'd get the Rebel XT which now goes for about $50 more on BnS. The tech is newer and you benefit from things like less noise and faster start-up and write speeds. These make real differences to your image production process. You also get an EF-S lens mount.
Based on my daily BnS trawling, $750 is probably what you should pay for a used 10d body only today. You can get the Rebel XT body only for around $800.
