I have one and I am happy with it. I agree with Joe about the build quality issues. The Canon is a much smoother lens but is it worth the extra ?

I tested both the Canon and Sigma at both of my local Jessops. I had set my mind on the Canon. Both my nearest store which stocked both is closed on Sunday. The next branch that is open on Sunday only had the Sigma. I noticed that this copy was much smoother than the first one I looked at. So I decided to save myself a few hundred £ and bought the Sigma.

Note a confession ( I am stupid enough to buy from Jessops ).
