Anyone have experience with the Canon EFS 15-85mm? My 17-85mm doesn't work anymore in the 17-24 reach, likely because of a defect in the aperture cable. Repairing is probably pretty expensive, and doing it myself is not an option. No experience, but I hear good things. Only serious complaint I've heard of is that everyone wishes it was faster given the price. If you're happy with the 17-85 and looking to save some bucks, I have one in very good condition that I could probably part with.
