I am looking for a scuba or a scba tank in god condition with a good hydro or should be able to pass one. I am going to use it to fill a paintball tank so just as long as it holds air I think it would work. I am not looking to spend a lot of money but I am not looking for someone to just give it away either. I know there are many on ebay but I figured if I can give the money to a board member then I would give it a shot first. An 80 cubic foot 3000psi tank would be great but anything will work.
