I have 2 cages from repti-racks. I'm very happy with the design, functionality and the service I received. I have 1 with a RHP (which I didn't end up needing) and they both have flexwatt for belly heat. The flexwatt heats through the pvc perfectly fine and my thermostat isn't set that high. They also aren't that heavy (24"lx12"hx18") and can be moved around pretty easily.
