I found a guy on craigslist awhile back that had 249 cf tanks used for a good price. however i lost his number and he doesnt currently have an add on craigslist anymore. it was a business in zephyrhills. anyone know the place im talking about or have an argon tank for sale? i want at least a 125cf but prefer a 249cf tank and also want used. new is just ridiculous in price.
