I own/use a Honda eu3000is generator for my outdoor shows. The last remote gig I used my generator on had: a 3-way FOH rig, four monitors, digital board, guitar and bass amp on stage, three drum mics, three vocal mics...no lights. There were about 500 attendees at this 5k race. The generator handled it well as it supplies 23 amps.
If the event required lights my 16 can par 38 (old school) lights could be powered by my Predator 2500 inverter generator.
I also have the parallel kit for the eu3000is if I need more electricity. My local Home Depot rents Honda eu3000is generators at $50.00 per day. With the parallel kit I can "join" two eu3000is' to use for PA/stage power.
A bonus to owning my particular generator: I have a switching panel in my house with an outside wall inlet. I can power my home with the generator when we experience major storms... (I've used it to power my home three times in the past six years.)
