I've heard a lot of people recommend rubbermaid set ups. I remember when looking at the MgReptiles site Matt also had set ups for sale. What perplexed me about these is how do you get a heat source on there w/o it melting the plastic, and how the very small enclosure (with no headroom, not that balls are climbers) also was curious to me.
Why do people recommend them?

Thanks!
