Inverter Generator Help Please

No, I've never camped where we're going before. It's called Nick's Lake near Old Forge, NY. The couple we're going with have camped there though. We usually stay at State Campgrounds with Electric hookups and the occasional private campground with full hookups. I've looked at the Champion generators and they get good reviews. I know most people suggest the Honda and Yamaha generators but to be honest, they are a little pricey for me and I'm not sure how much dry camping we'll be doing. I'm sure we'll do some but I don't know if it will be often enough to spend twice as much money on a generator.
