I live in Canada so unfortunately my options for cages is limited unless I make my own, or want to pay ridiculous amounts for customs/duties/shipping. I will more than likely end up purchasing from Greg West of Cornel's World Terrariums, as he is also local, so I would be able to pick the cage up in person. He uses PVCx. I purchased my Herpstat II from him a few months ago and was very pleased with the transaction.
Please keep us updated as to whether the blue light effects your snake at all.
