I got my sigma 17-200mm OS bout 2 weeks ago form this guy on ebay.
I also recommended him to another mate from work who picked up a 17-70mm sigma we both got about 50 off a brand new lens. He has plenty of stuff so drop him a message to see if he has one for a Nik.
He gets them that cheap for new cos their from Taiwan. litterally within 48hours i had the lens on my cam!
