I run a Millermatic 251 with a 15A spoolgun. I just bought a Miller self-darkening hood and I really like it. I inherited a Lincoln 225 AC buzz box that I use occasionally. My torch set is a Smith. I just bought a scarificing cutting tip which allows you to cut things off nearly flush, which was really nice for cutting off unneeded brackets off the 9" Lincoln diffy going under the 51. I also have gas welding tips that go from #201 to #209.
I had been toying with getting a TIG welder especially for aluminum but so far the spoolgun has been able to weld anything I require. IF money was no issue I would have a Miller Bobcat (I forget the model) that puts out 480 three phase for running pivots and testing high voltage componnets. A plasma cutter would also be nice:)
