Has anyone tried this:

Interstate Pneumatics WRCO2 CO2 Regulator - Solid Aluminum Body 0-125 PSI (Amazon.com link)

Interstate Pneumatics WRCO2 CO2 Regulator - Solid Aluminum Body 0-125 PSI (Mfgr link)

I contacted the manufacturer tomfind out if there was any supply pressure effect data for this regulator, but no response...

I might get one to test. ☺
