Hey icypepsi, I'd recommend exchanging it for another copy with B&H; they do a good job with returns.
If you're not 100% satisfied with a product, then it's worth replacing while it's free and easy. I know CRIS (the repair shop for Sigma lenses) can make focus adjustments to lenses, but I'm not sure if they can fix the issue where the lens focuses differently based on distance to subject.
Pentax and Sigma alike have ever deteriorating quality control (cutting costs in the bad market no doubt). Hopefully the number of returns (especially to the world's biggest camera store) will give them a clue that quality control isn't worth skimping. I had to exchange my K-7 twice before I got an acceptable copy...and I still have a banding issue on the sensor. Do the photography community a favor and demand perfection when you buy expensive equipment like that lens.
