Answered an ad on Craigslist. Three steel tanks, 40 bucks for all three. Guy says bring 'em back if they fail hydro or VIP and he'll give me my money back. Sounds like a no-brainer!
Take them to my LDS, one had already been condemned, but it was under some paint, so I didn't notice it. The other 2 are fine, back in hydro and ready to go.
I got two tanks and a spare valve all for forty bucks. All I have to do is hide my growing addiction from my wife!
