x2 regarding the T8! Each of my kids acquired a ball python last fall. We were keeping each in a 40 gallon Zilla Critter Cage (glass tank with screen top). Maintaining temps and humidity was a royal pain. Plus, my kids had trouble accessing the BPs because one tank was on a dresser and the other was on countertop, both of which were too high for my kids to reach into without getting on a stool or stepladder. Over the past several days, we assembled and set up the T8 and put the BPs in them last night. It is like night and day! The kids can easily access the BPs, and the T8, along with the Herpstat 2 that I purchased, are helping maintain the humidity and temps. Thus, I strongly recommend that, as your BP gets older and grows out of its current tank, you consider moving the BP to an enclosure like the T8 rather than another glass tank.
