I have a Coleman Powermate with the 10 HP Subaru/Robin Engine. These engines are rated highly by longtime users, run every bit as strong, quiet, and efficient as the Honda's. Not nearly as expensive.
It's rated at 5000 running, 6250 watts surge, and I can light up the whole damn house (All low wattage bulbs), freezer, fridge, furnance fan, TV, etc concurrently...no problemo. I calculated all the normally used electrical items to be around 4800 Watts continuous..

If you have a gentran panel why not get a unit that will let you live comfortably not only during a storm, but if we have a big natural disaster and services are cut off for an extended period of time?

During that '06 storm here in Woodinville we did not have power for 8 days, & it totally sucked leading to my decision to purchase this unit.
