20 gallons for me, enough to get my feet wet and realize that good beer is easy to make !
Got kegerator equipment for Christmas and just started fermenting first batch for the year, next step is all grain..
A friend of mine said he used a 60 watt light bulb to keep the fridge warm in the winter, with some sort of temperature coltroller that would cycle it on/off.
