Who manufactures Hobart Welders? Miller? I am considering a new TIG welder and the Hobart econotig 150 seems very similar to the Miller Econotig 150 and the price difference is a couple of hundred dollars. Is anyone here using this machine or the Miller or a Lincoln. I'd like to know what you guys think. Do you think its too small for the money? Its primarily going to be used in my own shop for small fabricating and repairs. Thanks, Mike
