Fermentation Chamber for Two Carboys, cost me $125

Got a 7 cubic ft. chest-freezer off craigslist for $50 and added a Ranco 2-stage temp controller (only using one) yesterday morning for $75. I set the freezer on the lowest setting (I found that the higher settings would cool down the freezer too much) and made a cardboard "seat" for my carboy, so it's not touching the floor or walls of the freezer. Temperature is exactly perfect ever since.

Anyone have any suggestions for additions or tweaks? I'm really happy with this setup and can't wait to brew another batch with perfect temp control.

Where did you get the dual stage ranco for 75 dollars?

Are you using two 6 gallon carboys or the 5 gallons?

I got the Ranco off of craigslist (already wired, too!) and was able to haggle the seller down to $75.

I'm using two 6.5-gallon carboys, which fit nicely into the freezer even with a bung/fermentation-airlock on top.
