I've only recently switched to a pvc cage, an Animal Plastics T10 (48x24x15) and so far I absolutely love it. As stated in the previous posts, humidity has been perfect, 55-60 with water bowl away from heat, will rise when bowl moved to hot side. We keep our home on the cool side year round so I use both flexwatt and a RHP controlled by a herpstat 2. Has been working perfectly for me with hot side 88-90 cool side 79-81 ambient 82-85. Cleaning has been easy enough.
