I have the reptile basics 2x3x1 and a 4x2x1. I think the 2x3x1 is perfect for the entire life of a BP. I started a hatchling in it and she's been doing great. It holds heat and humidity better than the APs do. The PVC is also shinier and cleans better. Sometimes some of the feces can stick to the bottom of the T8s, but the RB is so slick and sheen that all the filth lifts right off with minimal elbow grease.
The thing that really drives me nuts about the AP T8s is the sliding glass doors. Yeah, they sound like a great idea, but they are in kind of loose so whenever you walk by the glass rattles. I have to wedge Q-tips between to hold the glass in place. The RB acrylic doors latch in place nice and tight.
Now, I wouldn't buy an RHP from them though, but I'm going on. It's a slow day at work and you know how it is when you start talking about a hobby....
