I just bought a nice shiny new 5 lb. CO2 tank from beveragesfactory.com. They had good customer service were very prompt and very courteous. The tank itself cost $55. So, if youre in the market for a new CO2 tank check them out and if youre in San Diego even better because you can forego shipping costs and pick the tank up and get it filled there. Haha I sound like a salesman.
