Here are my three all time favorite cages (and you can't go wrong with any of them....I use all three for my burms, boas, venomous, monitors, etc.):
1) Habitat Systems: perhaps the finest cages on the market....well worth the money and they can custom make these abs plastic style cages to ANY size. We keep our exhibit burm in this cage
2) Neodesha: this popular cage, once out of business, is now back up and running in Florida. These are outstanding plastic cages that are higher than the vision models. I have used these longer than any other cage and love them.
3) Crescent Moon Creations: a newcomer to the herp market, these museum quality cherry wood exhibits are just that, exhibits. Beautiful and can be custom made to meet ANY spec.
Hope this helps. Rob
