I prefer the 220v ones and currently use a Hobart Beta Mig and have had a couple of Millers as well. Lincoln used to be good but the new ones are made in Mexico and quality went way down. If you plan on getting a 120v version, the Hobart Handler line is great. The bigger ones will weld up to 1/4" plate with ease. And like stated above get one that uses gas, flux is a pain and more trouble than it's worth.
