Does anyone have any recommendations for a good high quality CO2 regulator that will last a long time, and hold accurate flow? Its been a long time since I've bought one, and back in the day it was basically Milwaukee or nothing. Now there are 50 brands and the prices vary wildly. When I do a search on Amazon, all the options that come up seem to have at least a modest level of negative reviews... so where's the one that "just works" and lasts?
