Unless they put inverter generator for $500 - that would be the first option I would scratch.
I have build in Generac, that sucks propane running at high rpm all the time, so even I am forced to carry it with me, almost all powering is done with 900W generator I bought at HF for $80.
Due to small size the 2-cycle generator is quieter than build in Generac and it powers microwave oven and my coffee maker just fine. One at the time.
HF had sale on 2200W inverter generators. I had coupon for about $300 and was tempted, but that would make 4th generator for me and don't think I would pass my wife with the idea.
