I live in Atlanta as well! But I actually purchased a ball from J&J Reptiles over the Internet. They were super nice over the phone and answered all my (tons) of questions without making me feel like they couldn't wait to hang up on me! They were wonderful.
As a fellow Atlantian, I do implore you not to support the Petco, PetSmart, etc. types. I have been to a few PetSmarts in Atlanta doing volunteer work with adoptions for cats and dogs, and I always check on the herps. Their BPs are in the most horrible conditions! 2-3 to a tank and all the size around as a pinkie finger. I am afraid you might get involved with a sick snake that won't eat and it might not be the best experience for you. Moreover, it would only reward them for keeping their animals so poorly and overcharging for the poor things.
There is a herp show going on in October but I realize you may not want to wait that long! I am planning on going to it though. Should be better than the Repticon that I went to March 1...which was less than I expected to say the least.
