yeah...also consider what you will be using it for. i take a lot of outdoor photos(nature, backpacking, climbing & canyoneering). as a result, i wanted a slr body that could take abuse. the rebel body is plastic. its light, but fragile. the 10d is built on a metal frame making it very durable. if you already have ef lenses, then the 10d wont dissapoint you. i promise. ive been using it for almost a couple years and absolutely love it. an addition that i really like is the bd-ed3 battery grip. it allows you to use 2 batteries for longer shooting periods, and adds an extra grip & button for portrait style photos. this is an important feature in my opinion.
but again...consider your primary use prior to making a decision.
