I have been window shopping for a few months now. I've been looking at engine driven welders so I can be mobile. I can weld all processes. So my question is if you were to buy a engine driven machine, would you go new or used. My thought was that's if one were to buy used it's possible to purchase another's hidden problem thus leaving you with it. As to the new machine you get a warranty. Also would you go diesel or gas?

Thanks
