I just finished assembling my T20 model that I purchased from Animal Plastics, Inc. It was very easy to assemble and I am more than happy with the construction.
It is HUGE, larger than I thought. I knew the dimensions beforehand (72x24x24) but it's hard to get an ide of how gigantic it is until it's fully assembled. I purchased the additional belly heat and cam locks for the swinging doors, which is a nice additional safety feature.
My only problem is now I want to display it in my living room and I'm having trouble finding a stand for something so heavy.
If anyone is looking for a nice plastic cage I'd definitely recommend this company.
