    Ordered a Cummins Onan P4500i Saturday evening, called Monday morning for an approximate ship date, received an email confirming it would go out that afternoon, had delivery on Wednesday. Couldn't ask for more.
    As for the generator, I'll have to follow up with my experience; it's still in the box.
