I have mostly miller equipment and have used it with great success and dependability for many years but don't want to buy just because it is blue and there is the obvious premium in cost that seems to go along with it. Wanting to use mostly on 1/4" and smaller but occasionally maybe 3/8" I am looking at a new Miller 625 x-treme $1700 ish or the Hobart AirForce 500I $1200 or a refurb 500I for $999 through Hobart. Who here has direct experience with any of these options, I would consider others but consumables must be readily available local or by quick delivery mail order.
