I have the non-HSM version of the Sigma and love that one. Over at Nikonians.org, it seems to get good reviews. I haven't seen any on the HSM though. Although I can't speak much to this newer version, I do know that it weighs about 3 oz. more and has a little wider angle of view. The hypersonic motor is driven by ultra-sonic waves which is supposed to be faster and quieter so it sounds like a good deal. I think it's only $80 more at B&H than the non-HSM version.
