I bought one of the Firman generators you described for $715.00 delivered to my door from Newegg inc. It started right up and after break-in time I plugged it in to my rig and fired up the 13.5 air conditioner and it never even made tone change in the engine. No idea what the longevity is as I only have it for emergency. I pull it out to the tail gate of the truck every month and fire it up with the electric start and it always starts. Then I shut the gas off and let it run out 'til next time. Just looking at it, it seems to be a very well made little guy. Came with a very good manual and some tools.
