Found a nicNP e used 250 cf bottle on Craigslist https://pbase.com/9146gt/image/163224209--was being used to fill balloons with Helium at a party-shop. Ended up only paying $80. The cylinder has to be re-certified and tested, then it will be filled with 100% Argon to use with the TIG. I will give it a new coat of paint while I'm at it https://pbase.com/9146gt/image/163224230
