Bought the Wife an Upright Freezer

You can get a dual-stage controller for about $25 shipped off eBay. Lots of build threads on homebrewtalk.com, but I liked this one: http://www.homebrewtalk.com/f51/ebay-fish-tank-controller-build-using-wal-mart-parts-261506/

Electric work is my weakest skill for sure, but wiring it was simple. No reason I'd ever shell out $100 or so for a ranco ever again.

 

I have a ranco digital and it doesn't lose its settings when it's unplugged. I bought the 2-stage model from morebeer.com a few years ago and have had no issues with it at all
