My kegerator was given to me, along with a spare 5lb C02 bottle.I even get my C02 fills for free
I dumped about $150.00 in rehab/improvements.
I save $130.00 vs the case price for each time I buy a 1/2 keg.
It has paid for itself many times over
Even if it didn't pay for itself, it's all about having fresh draft beer at your disposal, not for the savings....
