Those regulator prices are very good! I'm almost suspicious. A 2
stage regulator steps down tank pressure twice. This allows the
use of a low pressure "needle valve". Much cheaper than high
pressure ones. For CO2 tanks you need CGA 320 fittings make sure
that's what these regulators have. Here in Canada 2 stage
regulators can go from $155 to about $250(Can.).
Caveat emptor (or something like that!)
