I found the three slot thing, only when I ordered it by price. $200. yipes. I don't have that type of money. I guess I'll have to just start figuring out how to make my own. It may be up to 6 months though. My dad isn't too keen on this bin idea. His dream cage is a 50 gal aquarium with an entire side made of water, then the other side just rocks. I have no idea why. This site has really helped though. *sigh* I'll have to get a job just to afford a better thermostat. (I couldn't edit my post- sorry!)
