I have a Boaphile Arboreal 3' long model that I use for my BCI's until they outgrow it. It is easy to maintain heat and humidity, easy to clean, and the RHP and UTH came pre-installed so all I needed was two thermostats and it was ready to go. The only downside is that my BCI's really don't make much use of the extra height; mine usually stay in their hides or burrow into the cypress substrate a bit. Now, that could just be because I've only used it for the younger ones and until the get larger/older they tend to hide more, and then they become more confident as adults so they would make use of the space.
