Sorry for the long post but I forgot to warn you. The caging and heating elements will be more expensive than your snake. You must be prepared for a big investment to startup. It's highly recommended that you get a thermostat, so you don't burn your snake. Here's a good site for thermostats and a lot of other stuff. Matt even has stuff bundled together for intial setup.....
