Yea I got mine from some avian keepers website because they were having a good sale. Next time I think I'll go through a herp site even if I pay a couple more dollars so I'm supporting the hobby, although birds are too.
Edit: Stuff is freaking awesome though, btw. I can't believe how far it goes or how useful it is. I feel good knowing my tubs are actually sanitized, although I never did see any germs on them before... :D
