I've got their catalog. (it's free!) Their cages are phenominal, but extremely un-affordable for me. It's very helpful towards getting ideas on how to build my own cage, though. I think the plexi-glass would be too stifling in the heat we have here. My poor AC is running around the clock right now just to keep my chins cool!! Plus, somedays when it just can't keep up, I put their desktop AC right next to the cage, and it blows into the hutch for them. They like it.
