I use boaphile cages...If I had to do it over again I would go with animal plastics, but they were the old hinge style back then and I didn't like the way they looked.

A 4x2 cage should be sufficient. There are lots on the market to chose from. They aren't that much pricier than tanks and they last forever with normal use.

If you want to go the cheap route, this is the time of year that places start carrying the big plastic christmas tree boxes, poke some holes in it, heat it, and you've got a cage. Animal Plastics even makes a rack that fits them.
