I am in the market for a new co2 regulator. I looked at co2 art, UNS, GLA, etc. I just don’t know which one is of good quality. I don’t care for all the fancy work but plan on using it for multiple tanks. Thanks

I think out of all those, GLA is probably the better one because of the needle valve, but I'm not sure, because their needle valve looks different from what it use to be. I think they all use the same regulator available on Alibaba. I hear that most of the regulators that you listed above are good, but their needle valves are difficult to adjust the flow rate. So whichever one you choose, if it is difficult to adjust, you can always upgrade it to a Fabco NV-55-18 metering valve. Otherwise, there's a bunch of guys here who build high quality regulators.

After all the forum reading if I hadn’t done diy I think I would’ve sprung for a GLA setup
