I've been reading other forums on extension tubes. I was about to buy the Kenko set, but then I read that they were not compatible with EF-S lenses. (I have a 10-22mm EF-S lens I was thinking about, and leaving my options open for the 60mm EF-S macro.)
Presumably, the the "Pro Optic Auto Extension Tube"s from Adorama are. Has anyone tried them?

| I know a lot of teleconverters are incompatible because the EF-S lens elements project back into the glass. Since extension tubes have no glass, I don't see why there would be any reason for incompatibility unless the mount itself is different. At worst, you might have to focus manually. |

From what I've read it has to do with the electrical contacts. What I was reading on DPReview was that for the Kenko tubes, you have to remove or cover one of the contacts with tape to get it to work with EF-S. Kenko recently redesigned their tubes, but on B&W, there's a list of EF-S lenses that it doesn't work with.
I had an order in for them at Hunts, but they called me to tell me their web price was wrong, so I took the opportunity to cancel the order. I did order the Pro Optic ones from Adorama, an they were signficantly cheaper, but now I am a bit worried about no-name brand tubes and putting them in contact with my new Rebel XT. :(

| Dagnabbit, NOWWW you tell me! I just ordered a single 25mm Kenko tube today from Adorama for only $6 less than the whole set you're getting. :-( |
