I’ve owned 2 GLA regulators. The first was one of their older model (new at the time) GRO-1 regulators that I bought about 5 years ago and sold a year later to fund a guitar restoration project. That regulator worked flawlessly the entire time I used it and the new owner never complained (sold it through another forum). The second one (PRO-1) has been in continuous use for the last 6 months and all I ever do is check the bubble counter fluid level and refill accordingly, which has only been once. Beautiful, great functioning, regulators that are worth the price if you can afford it. Yes, they are pricey, but Orlando will take care of any issues that may they occur. I’m really not trying to push a $300 co2 regulator on anyone. I do understand that that could be a car payment or a mortgage payment. Just, if you happen to get one, they work great and i don’t think you’d be disappointed.
Having said that, those are my only experiences using any Co2 regulator. I wouldn’t hesitate to use any of GLA’s regulator offerings if you can afford them and they have the correct fitting for your co2 canister. Having said that again, to go off of what Streetwise said, on other forums there does seem to be a lot of praise for the Milwaukee. Even the Co2 Art seem to work well for most people.
The point is, buy what you can afford be it $300 or $75. The next point is, injecting pressurized Co2 does take a significant chunk of change to get started. In my area, a brand new “first-purchase” 5lb Co2 canister is $90-$100 then $20-$25 for an exchange. A “decent” cheap regulator is going to cost you at least ~$100. A diffuser/atomizer/reactor ranges from $5-$60. Co2 tubing, solenoid timer, say $20. Even going “cheap”, I’d still be in it about $250. Understanding the limitations of your equipment relative to your budget is the biggest influence though. For me, the limitations of GLA’s regulators are worth the asking price. However, don’t buy something expensive just because other people say you should. Do GLA’s work? Absolutely 100%. But they aren’t the only player in the game and really, they all “work”. You just need to understand those limitations we talked about earlier and decide if those limitations are something you’re willing to deal with for the asking price...for any regulator (or any other piece of equipment for that matter).
