Do some research on the new T3i and 60D and you'll find that they are almost identical except for size, weight and ergonomics, and of course price. Unless you need or want a slightly bigger body with a bit more weight, the T3i would be cheaper but have the same features, including, I believe, the same sensor. Check out the preview for the T3i at dpreview.com as well as the review for the 60D.
