Need a larger tank of Argon/CO2

[Psychoholic]

I have a #1 tank I got from Shadow (along with his welder) and the amount I've been welding lately it's really not cost effective to keep going up and getting this filled, when it is a 6 dollar difference to fill this or one twice as big. If you have an extra 40 or 80 tank, I'd love to buy it (even empty).

Thanks!
