I am currently trying to piece together a kegging system as cheap and basic as possible. Since I am on such a tight budget I am looking for advice on where to get each piece co2 tank, keg, regulator, ball lock fittings and picnic tap as cheap as possible. So far the best price i've found is at learntobrew.com with their $160 one keg kit and $8 shipping but the co2 tank ships empty so its going to cost to fill it too. I'd like to see if I can piece it together for less though. If anyone can point me to a cheap source for any of the parts it would be very much appreciated. Thanks.
