I new less than you about camera tech when I first started shooting and I opted for a used EOS 20D from eBay. I've never had a problem with it. Unless you want to count that time I put an old flash that fires with 250V on the hotshoe. (EOS bodys can withstand 6V haha).


I've shot around with my friend's XTi and I would take my 20D over a rebel any day. Even the older xx-d bodies feel more robust than current rebels.


If you want to go xx-d though, I'd recommend the used or refurbished markets for EOS 30D s and/or 40D s.


Just my take on it.
