Jaycar Electronics has a
2kW pure sine wave 4-stroke invertor generator on offer for $899, which seems to me to be a pretty good price. No idea what it's like, but Jaycar has always struck me as being a reliable company offering good customer service so it might be worth looking at if you are after a generator. At 65dB it is nowhere near as quiet as a Honda or Yamaha, but you have to sacrifice something for a good price!
