All right, you've convinced me. I ordered the "Premium AQUATEK CO2 Regulator with Integrated cool touch Solenoid" from eBay - $79. Working on a CO2 cylinder from Amazon and a few extra parts. It will be a couple of months before this is all set up but I'm excited to see how it all works and the results.
Thanks again for the input, I'm starting to get my head around all this CO2 stuff.
