i am using a sterlite container for my bp and i find it even hard to heat in the winter. the sterlite or rubbermaid containers are really inexpensive and work so much better than a tank with a screen lid loosing most of it's heat.
just my 2 cents... as i'm new to snakes as well... but this forum has enlightened me GREATLY as i was going to use a glass tank when i started out... but i believe it was adam who told me: "aquariums are for fish, not snakes"
