Default NEW Sigma 70-200mm f/2.8 II APO EX DG HSM Macro Zoom Lens

Does anyone have any experience or thoughts on this lens?? Also what is the difference between this HSM and the HSM II..This is somewhat cheaper than the new OS version...

I can tryout this lens from a buddy selling it for $600..Anything to look for..ex focus speed..??

The II was for a new optical design. The original had 17 elements in 14 groups, including 4 SLD elements, while the II had 18 elements in 15 groups, including 3 ELD and 2 SLD elements. It seems the II was a slight improvement.
