If a portable unit as small as 2,000 watts is what you are looking for, the Honda EU2000i is a great little generator. Very quiet, high quality power for your electronics and the Eco-Throttle cuts back engine speed to just meet demand. More expensive but in the long run the features are worth it.
We use it to run the furnace, refrig, computer and some high efficiency lights.
