I have Freedom Breeders and they are great racks. The only problem if you get the hatchling rack you are looking at is in a few months they will grow out of it.

Why don't you look at a Vision rack, it can be changed from a hatchling to a sub adult to an adoult CB70 tub all in the same rack or have all 3 on different levels if you want. It depends what your needs are. Most racks are a one tub size rack, BP's grow fast and unless you want to have several racks for many snakes, i would check into the Visions, i have 2 now as well as Animal plastics and Freedom breeders.
