Toby,
I will put this bluntly...as you have admitted to being a beginner here...but made an "expert" evaluation.
Being a beginner, I'd doubt you'd know the difference. I too have welded with both units, considerably. The Miller is NOT smoother. Going around bad mouthing without understanding what you have isn't a good thing. The DX from Everlast is far smoother in MANY people's opinions. Yes, we send out a economy torch, but what torch do you get with the Miller? We offer other torches and another foot pedal made here in the US. I'm not sure what "crappy" customer service you received, but if you are referring to finding another price, that's something that you cannot blame us for.
