Another Okie on the board...that's good. What part of OK are you in. I go to school in Edmond, but I am in Tulsa on weekends.
As to a welder, you can get a good 110V mig for $500. I have a Hobart 135 (I think). It works great. I foudn it in the newspaper for $175 with a bottle. It works great. I haven't used a Lincoln, so I don't know about them.
