The Pulsar PG7000DOF is lauded as a generator to go for when power really matters. The generator has output of 7000W, and a 10HP motor. The main selling point of the Pulsar is its sheer reliability. However, for a machine that is a bit higher in price, the lack of a remote start system is a little disappointing.

The DuroStar DS7000Q is of sufficient power and reliability to make it the machine to go for if you need power backup on farms & ranches, or in construction, as well as for dealing with emergency powercuts in the home.
