I used to own one of the Sigma 70-300mm f4.0-5.6 Apo Macro Super lenses and it was pretty awful at the long end. I think my copy was the Apo Macro Super II. There are newer and I should imagine improved incarnations of it, so just be careful if you're buying second hand. Make sure you're not geting one of the older versions.
