Thank you everyone who replied and helped.
AirCo / West Penn Laco located on Stoopsferry Rd was both close, priced right, and helpful.
Chris, the operating mgr, is quite friendly and helpful. I even signed up to take an intro to welding class he hosts (its not a cert program - just a FYI intro type deal). Anyone else in the area should consider them for CO2, or Bev gas.
