Been using the lincoln weldpak....don't like it so I bought the migweld 140, welds better with fluxcore then the lincoln does. But anyways I've never had a mig so it's time to get some gas. Question is what's the best way to go about it. The whole lease and rent thing I get but I can't find a used bottle to trade in so I'd have to buy a new one and here that's like 300 bones. Is it that much everwhere?
