I have one of those little 1200W 2-cycle generators and recently had occasion to use it during a scheduled power outage. It ran surprisingly well, and easily powered the important stuff (HDTV, satellite receiver, a couple of lamps). Running it for about 3-4 hours it had used very little fuel and was quiet. I definitely recommend having one of these smaller generators to complement a big one. It was way easier getting it setup than dragging the 5000W unit out of the shed.
