Monster Cages or Animal Plastics?

[Vypyrz]

I'm curious about the radiant heat panels... Considering that I plan on using aspen for a substrate, would the RHP work better than flexwatt?

For an 18" tall cage in Alaska, I would recommend outfitting the cage with both. I would rather have the option and not need it, than not have it and mess with installing it later.

Are AP and MC the only manufacturers that you have looked at?
