It depends on what your budget is....
A lot of people like myself who were sick of replacing bulbs and dealing with humidity problems in tanks (for adult BP's) will order an animal plastics T8 or T10, and run a Radiant Heat Panel (RHP) for the heat source along with a reliable thermostat.
AP T8 - $165 + $48 shipping
RHP - $120
Therm- $100ish
Figure on $450 at the worst for the complete setup, some people like to add flexwatt underneath as well, but I personally don't find it to be 100% necessary. Just a very nice addition. It's like a Chevy vs a Cadillac comparison haha.
I haven't ordered from them in year but I've heard Animal Plastics has quite the waiting list now for their cages, so keep that in mind. They're busy for good reason however...
What I just listed is the care free... but expensive option for sure, but it's a proven one and a lot of people like it. I'm going on nine years of the above setup without having a SINGLE hiccup. No bulb replacement needed, no covering of your cage, no damp/wet substrate needed to keep humidity (paper products work fine in AP cages, as they hold humidity VERY well from your water bowl alone)
