Where to find CO2 cylinders (other than LFS or MO)

[JoJo]

Hey Guys,

The valve you're talking about, is it the shut off valve usually found on a co2 cylinder?? I have a 2lb cylinder ,from a Sodamate pop machine, that is fitted with a brass valve that has a spring loaded pin in the middle. If the pin is pressed in, co2 flows and shuts off when released. In order for me to mount the regulators onto the cylinder, I must first change this valve. Where should I go to obtain one?? Thanks!!
