My only guess is that they must make a lot of money off rentals, and not a lot of money off private sales. Oh well. I think I'm going to try the fire extinguisher idea (look into it some more) and try the OTHER Air Liquide office in town to see if I can get a valve and a hydrostatic test. (There are two. If I call the same place again the guy will remember me since it's been the same guy I've talked to twice in a row now.) I'll play up the beer brewing angle. Thanks for the suggestions guys I really appreciate it.
