Most UTHs, even when functioning normally, will get way too hot for BPs. Not all reptiles are created equally in regards to heat tolerance, so we need to account for that as keepers. Here's a thread going on right now about just how hot they can get without a thermostat: http://ball-pythons.net/forums/showthread.php?t=226513.

As far as what a thermostat looks like, check out the glass tank set-up thread in my signature. It shows several options with various price points. I have no idea if Petco carries them at all. You'll likely need to look online for this one.
