What's a good intro welder for subframe connectors?

Millermatic 211 is an awesome welder and will run off 110 or 220. Not the cheapest but the best bang for the buck. Millermatic® 211 MIG Welder
If you only want the cheapest and dont care how long it lasts just get a harbor freight mig.
I'm really afraid of the quality of Harbor Freight stuff. Hate to have a expensive paper weight.
