Buying a brand new keg guarantees you a flawless appearance and years of service. If you would rather not handle a keg that has had a past life as a soda keg that has been shipped back and forth between the 7 Elevens of the world, this is your best option. 8 1/2" in diameter and stands 25" tall. Has the more common ball-lock fittings. The rapidly rising cost of stainless steel plus the weak dollar have contributed to significant increases in the price of new kegs in the past year.
