Thanks guys...
I am looking at the regulator, etc Custom Aquatics is offering (made by
Milwaukee).

This is the product description:
"CO2 Regulator with needle valve, solenoid valve, and bubble counter. Dual
gage regulator displays output pressure and bottle pressure. Standard
American CO2 bottle connection."

It is $20 cheaper than another site I found the exact same set-up.

Is that what I'm looking for to attatch to a tank to be off and running?

Thanks,
John
