If you really wanted to go that route, your better with a 2-stage, and one that has NOT been used with any gas other than CO2 or Oxygen (you wouldn't want any Acetylene residue getting into your aqaurium). Some of them can be converted over by changing out the nipple, but some can't. The Victor Two-Stage 250 series are an example of some good ones.
I'm going to forward you a PM I recieved from Left C on this very subject...
