Hey Nathan, et. al.,
I live in Chatham and work in H'boro. I got my original equipment and first few kits from the Durham store and enjoyed my visits there, but the math doesn't work out to drive there to get supplies.
The best place I've found is MoreBeer out of California. They ship free for orders over $59. Austin Homebrew Supply has flat rate shipping of $6.99, so still cheaper than the gas to drive to the "L"HBS.
Good luck! It's great to hear from the home boys on the site.
