Wow, you guys are great. I'm looking at this tub right now, seems like it meets the requirements:
http://www.sterilite.com/Products/Catalog/1986_LG.jpg
It's the Sterilite 1986. 40 quart box, 26 1/8"L x 18 1/4"W x 6 3/8"H
So I think I will get two of those. And I will go shopping for a good thermostat and a UTH.
Should the UTH go under only one side of the tub? I know for my geckos I heat one side, is it the same with pythons? As long as the heated side is 92-94 and the other side 82-84.
Also, can someone send me a link or a proper name for these "clips" from an office store I can buy to hold down the lid of the sterelite tub. That would be great.
This is all a huge help and I'm even more excited to get them now then I was before! I'm going to get the tubs and equipment all setup so when I get the pythons in a month from now everything will be ready.
