If your in the price range for Freedom Breeder or ARS...
Look into Kreature Keeper. www.kreaturekeeper.com
They are Biggers and Calaham. The same company that owns Mice Direct, where I get all my rodents from.
Once I get bigger into the snake industry, Ill be using Kreature Keeper.
ALSO,
Vision makes pretty good racks on the FB and ARS level. They are built cheaper though, being WAY cheaper. But till OK, but I dont like them, saw the new models today in Daytona and didnt like that a kid could run into it, and knock it over....
