As far as efficiency of a chest freezer goes, I used a "Kill-A-Watt" meter on my new (to me, ~2-year old unit from CL) Holiday 5.0 cubic foot freezer held at 45F with a Johnson A419 controller.
Looking at about $0.75 per month to run after averaging >1 week's energy use. Currently using picnic taps until I finish this - so opening more than I will when a tower is installed.
