I know what you mean about the cost of tanks. I have a small oxy-acetylene welding set and a set of nitrogen tanks for leak checking refrigeration systems and I think I have about $800.00 tied up in them. Now that I'm retired I don't do a lot with them, but plan to use the welding set occasionally for odd jobs. I figure to use the dry nitrogen for painting.
