I keep my room pretty warm, as I have two snake racks and the gecko (tokay) in my room. We also keep the temps around 70~F in the winter. The boa's enclosure won't be by a window.
Yes, they were the only ones I looked into. I couldn't find any from Reptile Basics, and I couldn't think of anywhere else to look (it was like, 2am when I was shopping, lol)
