ProStar PRX31277 brass dual stage regulator $39.99 on evilbay. Maybe someone should hit it up.
I'm thinking about getting this one. I'm wondering if I could just install a 3000 PSIG gauge on there. I can't find any information on this specific model. I checked their website, and it's not listed. Do you think it'll work? What issues are you talking about.It's listed as parts/not working, and the inlet pressure gauge only goes to 400 psi. If it did actually work, the gauge would blow as soon as you hooked it up. Which probably wouldn't be a problem functionally, and you could replace the gauge with something more suitable. But it has issues.
