Advice on wide angle lens for my 650d

I got the Sigma f/4-5.6 for my 600D/T3i & it is a very nice solid well built lens. I read all the reviews of lenses before I buy as a rule, but often the problems that the tests point out, are not that noticeable in real life shooting. Most can be fixed in PP anyway. I now use the Sigma on a 7D & it gives excellent images.
