I have a miller dynasty 200dx, it's a great unit, its relatively light and portable, will run on 120v or 240v or 360v ect... All just by plugging it in, which is nice when you drag it to friends houses and shit. The only draw back to it I have found is that if I want to do thick aluminum. Up to 5/16" is ok, 3/8" is really pushing it without preheat. I think the only thing more that I would want is more amps, but then I would loose the portability, so kind of a toss up. The only other draw back is price. For the ~$3000 all you get is the dynasty 200dx box and a cord without a plug. Still have to add a torch, a remote control (hand, foot, whatever) Cabling, ground clamp, bottle regulator, consumables, ect... I was around $5000 Cdn all said and done. Where as my Miller180 autoset mig was like $900 out the door with a cart and wire and everything. Apples to Oranges I know, but the Syncrowave is more like that.
