Reptile Basics Inc is where i got mine from. You will not find better customer service than Rich from RBI. That is a fact, not just my opinion.

Ive also heard really good things about AP, mainly from aaron, lol jk jk aaron. They seem to have quality products at reasonable prices. ANd if you wanna spend a little bit more then vision racks or freedom breeder racks would be good options too.
WHatever you decide, be sure to post pics of the snakes in their new condos (tubs)!!!
