After being beat about the head and shoulders by Dutch I've decided on an AP 4'x2'x15" cage with an RBI 40 watt RHP for basking. After a lot of browsing on this forum I think I want an Ultratherm Undertank Heater for the cool hide as Rich thought it might be close with the 40 Watt RHP to maitain the cool spot temperature by itself. My question is what size pad?

As an aside, I sent emails to, AP, Boaphile, RBI, Vision, Showcase, and Pro Heat with various questions. Rich at RBI got back to me in 1/2 hour and answered 3 more emails all within an hour. AP got back to me in 3 hours, Showcase in about the same. I still haven't heard fom Boaphile, Vision, or Pro Heat, for Boaphile it's been 4 days, the other 2 it's been 2 days. Just an FYI
