Argon Welding Bottles

[RACE427@aol.com]

Someone in this group must know where I can purchase a large Gas Welding 
Bottle to store Argon.  I want to own my bottle as I do not always use a large 
enough quantity to justify renting a bottle.  Would prefer to purchase mail 
order 
or through the internet if this is possible.  Will also drive out to make the 
pickup.  Any help or leads are greatly appreciated.
   Anxiously waiting for my Lincoln TIG machine to arrive.

      Thanks for your help!!   Tony G  LI,NY
