House will be climate controled, but I'm sure during winter when I'm being cheap and keeping it at 64, I might run into keeping it hot enough. (75 thru 90 degree's with a 130degree bask spot, 70% humidity)

The doors does sound like a really cheap option. And if hollow I imagine if I wanted I could inject a foam insulator if need be. May not fit the bill for keeping the build "pretty" but I'll look into it when I do some window shopping later this week.
