You could always build your own? By the time I would have added shipping the price is similar. With heat, glass, 2 PVC 4 X 8 sheets, misting system I am probably about $1150 I just priced out the same size AP cage shipped with all the same options and it was $1123 without the cost of the heat panels ($200) and the misting system ($150) and my material is 3/4" so IMHO a little heavier duty. And my glass is tempered bronze tint on rollers not just sliders. On top of that is my Herpstat 6 but I would need that in either case and adds about $500 with humidity probe. I went with the herpstat 6 as I am waiting (did I say waiting!) for a 24" X 24" X 36" tall AP arboreal cage for a not yet purchased Emerald tree Boa. So it will control and monitor both cages for heat and humidity and all lighting on one zone, humidity both cages, 2 heat zones in the big cage and 1 heat zone in the AP cage.
