Great price!......is this Smith Oxygen Regulator 30 NEW? Is it reconditioned or rebuilt? I see there is a review posted here that says that the customer bought this one from you and it drifts and doesn't hold a pressure setting correctly. I have the same problem with my OLD Smith Oxygen gauge and need to replace it but I am holding back from purchasing this one because I am not sure if you are selling a NEW or REBUILT REGULATOR. Please let me know as I am in the market for ONLY a NEW Smith Oxygen gauge for the Little Torch in the 30 Series size. Let me know and let's do a little business! Thanks, Ken W
