I purchased two Harris dual stage regulator. Easy to attach to the Clippard Solenoid. All I had to purchase was a female CGA to male NPT adapter that cost around 3USD.
I used the Clippard Solenoid from Rex Grigg (31USD + s/h).
I got them for a pretty good price (75USD each + s/h). I've paid around that for single stage units. For sale at e-bay (100USD one unit).
Introducing my Harris Calorific 3-CD100F-320 CO2 Flowmeter dual stage (industrial grade).

I'm going to use it with a 50lbs cylinder to inject CO2 to four tanks using a four port manifold, also from Rex Grigg.
