I really screwed myself by picking up the Canon 30d at Best Buy this weekend and now it has me wanting to upgrade from the Rebel XT I have now. Theres nothing wrong with it, just like the way the 30d felt better in my hands. bandhphoto.com has some used 20d's (even better then the 30d) for 800 bucks, in like new condition. What do I need to worry about when looking at them? Is there older 20d's that are bad? Should I stick it out and wait for a good deal on a body as I already have most of the lenses? All advice is appreciated!!
