If you want to stay in the $300.00 range contact Mark with Everlast, see what kind of a deal he can give you on a Power Arc 200. I have one, for the money I would love for someone to show me a better arc! It will make stacking 6010 childs play. And runs 7018 great! If I had it to do over again I would buy the Power Arc 300, to get the adjustable hot start, and arc force.
