What's the ozbargain way to get argon and the bottle? Cheapest and most convenient way I've come up with is bunnings, $200 deposit, and $99 for gas. Don't have to pay recertification etc. There is a company in WA that does it cheaper, buy they are in WA and I am not. Anyone got someone they recommend?
Edit - should have specified, size d, maybe e.
Have you tried BOC?
