I have the T11 from AP and it is great.
Get the belly heat but you will need a good thermostat to control it. I use a Helix DBS1000 but they are costly about 100-130.00 depending where you buy them. But they are IMO the best. But any good T-stat would work. I got into Helix from talking with some breeders at shows and AP cages recommend them also.
With the T11 I would get and I did get both cut-outs for lights, one on each end. When you order just ask for them to ship the cut-outs of plastic from the light holes. If you don't need the lights just pop the cut-outs back in.
I got the sliding doors w/ the lock and I also had them drill 1/2" holes on each end about 6" from the floor to slip my probes for my T-stats thru. I also had them engrave my bp's name on the front of the cage.
The holes, cut-outs and the engraving was no charge and the customer service is second to none.
And as for the hides, I agree w/ everyone you have to have 2 hides, one on the cool end and one on the hot end. That is very important.
If you have any more questions about AP just send me a message thru here and I will help ya all I can.
