If you want to buy supplies cheaper than your local shop and get excellent advice, try HerpShop. They have a range of heating options and thermostats, plus excellent light cages. All stores in my area are much more expensive. Brian will give you good advice if you give a good description of what you are using, animal, etc. Like many others, I prefer a ceramic heat emitter (controlled by probe thermostat) and a normal flouro light globe. I've got an enclosure with a heat panel and flouro bulb, too. My spare enclosure just has a red incandescent for heat and a bit of light - it's not a display, but just someplace to park an animal for a few weeks when necessary.
