Best overall regulator for the price

After using many different regulators and always eventually have some sort of issues. I've realized sometimes we're better off paying a bit more to get something reliable and well thought out. The expandable manifolds are amazing. No more ugly DIY splitters, no inaccurate needle valves or poor reliability. Co2 Art elite regulators check all the boxes without the huge "GLA" premium.
