Harbor Freight has them from around $180 U.S. and up. I've had one for years and it will do light duty work, although the first one I bought failed after about a year (which they replaced). I would recommend looking for a used name brand MIG welder like Miller, Victor, Lincoln Electric or Hobart though. You would be money ahead in the long run. We bought a used Hobart Handler 187 with tank of gas, cart, 40 foot extension cord and tool box with tools for $600 and haven't touched the HF machine since.
