What are you waiting for? I've heard that 140s are plenty of welder for most home projects. I have two friends with Millermatic 140s and they won't give 'em up for anything! The guy I bought the TIG from also had a MM210, and he had the same feelings. I asked if I could buy that while I was there and he said NO WAY! Ha Ha! Post up when you get going. Let the addiction begin!
