I felt really crafty one weekend and decided to try to create some gecko cages out of a walmart bookcase into a gecko cage...and this is what I got (please keep in mind I suck with tools and anything sharp so I was quite excited). It's heated by 4 inch flexwatt plugged into a rheostat, tile for flooring (wash clothes now too). Plexi-glass is used for the doors and an added lip inside. Please excuse my ghetto cage separators lol.
