My main hurdle is trying to find a cost effective solution for the power supply since I got some complaints about excessive noise with the portable generator.
The Honda's and Yamaha's will be your best bets, as you found out.
We use them at the racetrack and they're superb.
Craftsman and similar ones will shake the fillings out of your teeth, make you go deaf, and create a long list of enemies in very short order!!
I know renting equipment isn't ideal, but have you looked into that?
Baker Rentals at Fairview / Baker in Costa Mesa offers the Yamaha 6500 and 10K generators.
The 10K is only $80 per day.
Regarding a helping hand...PM sent!
Hope it helps!
