Fridge Incubator

[Bighead]

I finally decided to sacrifice my beer fridge and turn it into an incubator. It took me a while to decide which addiction was more destructive. I chose reptiles so now thats where I'm focusing my efforts. Hehe.

So, let the fun begin. What is the best way to do this? It's a rather large mini fridge- 21" x 21" x 33" Should I use an aquarium heater? Light bulbs? Heat pads/tape?" I remember seeing a thread on this a while ago, but couldn't find it. If somebody could give me the link that would be awesome. Are there any websites about how to do this? I will be sure to take pics along the way and post them. No digicam, so they will be delayed a bit, but oh well. Thanks for your help in advance.
