The rubbermaid/sterilite enclosure solution is one of the easier solutions out there for keeping snakes. They hold heat/humidity very well, and kept correctly, are very secure. They're also very cost and space effective. With a six tub rack, you can go to Target and purchase additional tubs to replace the ones that are dirty and have new, clean tubs to interchange with the ones that are currently being used.

With even a medium sized collection, there's no other way to go IMO. I would be lost with tons of glass vivs all over the place!

Hope this helps!
