The biggest, most-powerful model. Comes with most of a tank of fuel (recent). $650 new. Used twice. Barely used. Needs either an adjustment, or tune-up. Home Depot thinks it needs to have the filter or jet blown out. I simply have no time or interest in fooling around with yet another tool whilst I try to finish building my house, and it's almost warm out! It's a beast, and warmed up my 3,400 sq/ft house in the dead of winter, with no insulation so that I could wire and do other hand-specific tasks. Delivery could be possible.
