What do you consider wide angle? What do you consider cheap, for that matter?
There's not too many options for truely wide angle on a crop camera. Canon has the 10-22, which is a great lens, but it's not terribly cheap. I know when I bought mine I thought $700 on a lens was a ton of money. Sigma has a 10-20 for less, I don't know much about it, but I have had Sigmas that I liked in the past. Tamron has a 10-24 in a similar price range.
