Thanks for the welcome guys. I guess I got kinda antsy waiting for a reply so I went ahead and ordered an 11"x11" Ultratherm and a thermometer from ReptileBasics. I'm planning to hook the Ultratherm to a dimmer and see how the BP likes it. There's no major temperature swings around here so I figure I don't really need a thermostat and a dimmer should be enough.

Sunny1: I live in Quezon City which is in Metro Manila. Subic Bay is still there although it's a mixed industrial/resort area now. And the jellyfish are a seasonal/regional thing. If you tell me when you're coming, I can point you to a kickass beach with no jellyfish.
