I'm sort of in the same questioning place you are, although I dont have a BP yet. From what I've been researching an RHP in a PVC tank is an excellent and safe way to keep the hot half, hot. Use a thermometer to control the heat with the probe on the cool side. RHP's won't burn the snake. I belive a 40watt RHP would be best. Delending on the PVC tank you buy, you may have to install it yourself. This will require drilling some holes. But again, Im really before a beginner at this! I'm sure someone more qualified will give a definite answer. Im interested in this question as well.
