Miller here, Lincoln and Hobart are good as well. My brother who is a retired union pipefitter always said pay once, or you can pay two, three or four times. He also said ask who is more likely going to be there should I you need parts in 5 10 or 20 years wink
Also, getting a machine to do 1/2" plate and sheetmetal is going to require a good 220V source.
