Wanted to see how much interest in old propagne tanks there was. I have a local guy with a boatload of them I can get I think. I made my own as well as 8 others. Not trying to make this a sales thread, but I think allot of you are looking for some. I'm pretty sure they would be at a reasonable price, but you have to figure out how to get them. These things are really heavy and hard to handle. And if you need to make a piping change and need to drain some water, the smell is terrible. Other than that they work great for storage or a buffer zone.
