Good place to buy tubs online?

Hey everyone, what's a good website to buy tubs from? I'm looking for something large... it's going to house a baby red tail boa. Also, what is the best type of UTH to use with a tub? And will a Rheostat be good enough for it until I get enough money for a better thermostat? Thanks!

Vision products (http://www.visionproducts.us/htm7/tubs.html) has tubs that are a little thicker than what you buy at Target or Walmart for around the same price. In addition, they don't have any ridges for dirt to get stuck to. I just ordered their 41qt for an Animal Plastics rack.

For a thermostat, I use a Helix but I've heard that Herp Stat is also good. I would not trust a snake to a cheap rheostat, too much temp variation. Spend a little up front and save down the line.
