So I have been looking into a few cameras and was thinking about picking up a used canon. It seems to me that the 20d holds a few slight advantages over the XT. 1/8000 shutter v. 1/4000, 5fps v. 2.5fps, and a couple extra focus points. All else being pretty much, equal, Can anyone give me any insight as far as other differences, comfort, and ease of use? I guess this might just come down to personal preference and price, but Id like to know if there is anything that I am overlooking.
