Where are you located? Mac Gases in Willow Grove is fairly easy to get to from the Willow Grove turnpike exit. He has Saturday hours from 9-3 but I would suggest calling. I just got a 20 lb tank with CO2 for $55. I believe he said refills would be about $15.Hi everyone. Im looking for a CO2 cylinder in the Philadelphia area. Where did you guys get yours from? Is there any store I could pick up a regulator from too instead of ordering it online? Thanks.
