i got the uth with mine and the swing doors instead of the sliding. i thought the swing looked nicer, but it's got less of an opening to get stuff out, which can be a pain sometimes. i didn't get any screens on the top because i don't use lamps at all. i got locks, just to be safe, because i don't trust the little plastic guards that come with it. then for temps, since i can't afford a nice thermosat, i bought a $20-25 foot dimmer for a lamp at ace hardware. it works well, i just have to keep my eye on it constantly. and as for humidity, i'm not doing anything for it because mine's a bit high right now. it holds it really well. i have to see how it does in the winter because it gets dry here, but as of right now, i'm trying to figure out how to keep it down...and they threw in a basking shelf for free...and she just likes to wedge herself in between her hide and the shelf, so that's cool. i hope i answered all of your questions. if you have any other ones, lemme know!
