Japan made generators, Honda or Yamaha, will cost you a bit more up front but you'll never have trouble starting one, they are quiet, they have inverter technoligy that makes them more fuel efficient, and they have cast iron cylinder block sleeves so they last. You'll have no trouble selling one down the road for good resale value if you ever don't need it anymore.
If you get a 3,000 Watt Generator you'll be able to start and run the AirCond too, but the down side is that at size it gets very heavy to handle by one person, and may become too large to fit in any storage compartments. That's why a lot of folks that want to run AirCond go with two 2K generators and a special cable that allows the two generators to run in parallel sync mode and have a 30 A shore cable outlet and be able to split the AirCond startup current and loads.
