I believe you can use the newer 10-20mm f/3.5 on APS-H as well but you will have some serious vignetting till about 12mm.

I had a 12-24 and my copy suffered extreme softness down the right side, had read a few reports of issues, seems like a good lens if you can find a good copy.

Sigma 15-30mm. Sharper, faster and cheaper than the 12-24 but not as wide obviously so you decide how wide is wide enough
The Sigma 12-24 EX DG is a fantastic lens if you get a good one.
I would suggest either going and trying it out before you buy or buying a UK stock version so you can return it to Sigma if not happy for recalibration.
I have always regretted getting rid of mine and on my 5DMk2 it produced images like these and on my original 5D it produced these.
Bearing in mind most of these were at 12mm on FF (mind blowingly wide) then on a 1.25x crop as the 1Dmk4 actually is you will get even less distortion and vignetting and an approx focal length AOV of about 15mm.
I ended up getting the Tokina 11-16mm for my 1D MKIV. Apparently it does vignette from 11-13 but after that it's fine. Should be here this week so I'll let you know.
Looked at the tokina 12-24 and the sigma, but I wanted something a bit faster
I had the Canon 10-22mm on my 7D....it was the perfect setup really. Its a bit of a gamble and I might have to settle for a 12-24 slower lens but I thought I would see how this works out

OK, my impressions and results. My impressions are better than expected. Even at 11mm you could probably crop out the vignette. Nice and sharp lens too...very happy purchase.
