Sounds like a good idea. I'll check out those brands. The only ones I've seen looking around are the cheap ones that I'd be afraid to leave on for very long. Even if I have to order one, it'd be worth it.
Geez... My old house was log, and I'm just realizing how well that held the heat in. Luckily all my other reptiles are native to the area, so I only really have to worry about changing my equipment and stuff for Trevor!
