I actually have a Beophile enroute. I was told, if I keep my house below 72 degrees, which it is, then you should use under tank heating (WITH a thermostat, flexwatt without one WILL melt the plastic and burn your snake) and use a radiant heat panel.

What turned me off from AP was being told NOTHING comes set up, you have to put it all together yourself, and even wire the flexwatt I believe. You really can't go wrong with either, but buying a RHP may be beneficial to your snake if you keep your house below 72-75 degrees.
