I ended up taking the Brute back and getting the Ryobi one I posted. It has a 3 year warranty vs 2 year and a 4 gallon gas tank vs 3 gallon.
Those 2KW stackable champions only have 1 gallon of gas. Pair 2 and you have 2 gallons of gas. I would guess you might get 2 hours of run time at full load. It should also be noted it's only 1700 running watts. x 2 is 3400 running watts.
The one I got for $400: http://www.homedepot.com/p/Ryobi-3-600-Watt-212cc-Gasoline-Powered-Portable-Generator-RY903600/206041609
Will use with my muffler box (hopefully it fits) to make it as quiet as the expensive hondas. I had one side by side a couple years ago at the fest and the guy couldn't believe how quiet it was.
