Argh! If I didn't get a 600D recently as 2nd body to 7D, I'd be all over this!
Actually, if I got it, sold the 600D+17-55 (as used) that means I could get a body upgrade and probably still have a small profit. Someone talk me in/out of this??? Before you ask, I already have the 15-85 and for my needs the extra range is more useful than a shorter f/2.8 zoom.
All assuming they do sell them at that price of course.
