Man, I would hold on to that sa200, untill you are sure you like that 200 d , If you have'nt welded with it alot allready. I not trying to sound like a jerk, I've had one on my truck for two weeks and its not the same welder as your sa200. I have'nt gotten used to the way that 200d welds & I might put my sa200 back on my truck.
