You can usually pick up a good machine at pawn shops, the one I run isn't a beginner model but you can get a small 110 millermatic or Lincoln for around 150$ most of the time. Just make sure it can run a shield gas. The non shielded flux core only machines are junk imo. As long as you can run a .30 wire with a shield you'll be good to go.
