Co2 Needle Valve

[tackful]

Hi,
Where might I find a reliable one? The one I have does not allow for fine adjustment. Thanks.

I read about cheap co2 regs is that the needle valve is impossible to set. Co2 regs seem rather modular. So why not get something like a WYIN CO2 Regulator off of aliexpress and then replace the needle valve with a decent one? Any reason why this is a bad Nox Vidmate VLC idea?
