David, I've been using the 10-22 (for a shorter while than Ted :-))
and it's a great lens. If you shoot digital, and are interested in
high quality wide angle work, get the Panotools plug-ins from Kekus.
They allow you to fully correct for distortion, and their software
now has databases that include the 10-22 on the 20D.
The 10-22 is about equal in quality to the 16-35 Canon, scaled down
to the smaller sensor size. With proper post processing it produces
outstanding results.
