If I had to buy everything then it would have been pricey/ I had some friend who like to drink Coors Light and drank up all the beer and gave me the bottles and taps from them. I then modified those. I do have one Tap A Draft tap that I left alone for portability. I had to purchase the paintball tank and regulator.Kmcace. Didn't you're system all adding up get somewhat pricey? Isn't each of the taps or dispensers like $40 alone?
