I don't know if space is an issue for you but for that price you could get a temperature controller and a chest freezer for much less. I've got two chest freezer setups, one fora kegerator and one for a lagerator. I got both of mine used for under $50 each. Temp controllers were about 65 so for two setups I spent about $230. Holding only two kegs doesn't offer much expansion room as your brewing hobby grows either.
