If you're going to go the Honda EU route, another potential solution is to buy one or two EU2000is generators instead of single EU3000. You'll pay a little more ($1k each versus $1800 for the single larger unit) but there are advantages to be had. The smaller units can power a small system quite capably, and they only weight 40-50 lbs versus the two-man-lift 140 lbs or so for the big-boy 3000. And you can gang two 2000's together for 4k watts if necessary.
Just a little flexibility for those of us that don't have crews of people to carry stuff around :-)
