Need a rack

So I got these two dumeril's boas that are gradually outgrowing 10 gal tanks. I also have a new snake on the way, and I'll eventually need something to keep adult house snakes in. Sooo...I'm in the market for any kind of rack system for 32 qt tubs.

Besides buying the materials and making one myself (which is a last resort if finances run low), what are your opinions of what I should look into getting?

Animal plastics? vision? boaphile? any others?

I can only speak for Animal Plastics since that is all I have experience with. I have an AP cb70 rack and it is great. One thing I would recommend is getting the casters. I did not and it is pretty difficult to move it by myself. That being said, I have heard good things about all of those companies.

I love my RBIs.

I just got some RBIs, they look so nice and work great too! Do not forget that even though ap is cheaper, it does not include tubs.
