I'd alos reccomend a nice display cage rather than a glass aquarium.

After using a 10 gallon for the last few months, I'm investing in a T3 from AP. It's too difficult to keep heat and humidity up in glass tanks. I could keep it warm with a stronger bulb, but then the humidity drops way down. I'm using a UTH as well as a day and night bulb. I'd check out Animal Plastics and see if you could afford one.
