I’m not sure if they’re on amazon, but you can find ones on aliexpress that go 0-30.
In my opinion, 0 – 150 psi range doesn’t give you enough resolution to dial in correct pressures for carbing and serving. They do make them in lower pressures (0-60 psi), but even lower would be nice for kegging and dispensing applications, especially when you compare prices to some of the other expensive mini co2 regulator options.
