I have a couple generators, I finally bought a Honda for flying field use. I wish I had done that years ago. Buy a Honda and forget it, one of the best purchases you will ever make.... we even use it for small stuff around the house when the power goes out.
The best price I have seen on a day to day bases with no tax and free shipping is Generator Depot;
