Anybody used the newest style model? Trying to pick up something decent for the garage, and like the idea of having a multiprocess machine. We used Lincoln Pro-Mig 350's in school, and would like to stay away from them, as I want something with High Frequency. I haven't thrown the idea of buying a decent tig, and mig separate, but am growing fonder of saving space. Also, does anyone have any real experience with the Dynasty models? Trying to decide if the extra coin is worth the adjustability and program options.
