Thanks!
Got them for $30.00 each on craigslist. I had been watching the local adds for something cheap to use as incubators for a while. They came with the shelving and were actually still working wine coolers. We almost felt bad not using one for its intended purpose. Still, we are guessing we can get 5-6 egg tubs in each, and the flexwatt was relatively cheap. The flexwatt came from Reptile Basics. Altogether I would say it was a great deal, and it only took us about 45 minutes to thoroughly clean them and install the heat tape.
