Talk about early adopters! I preset my buttons to any station that did not play music, sometimes listening intently towards the morning farm report. (If you haven't tried it they provide you with a window into an entirely new marketplace.) For me music was continually deteriorating and talk was continually improving. No contest.
Fuel Consumption - The sourcing cost of 400Kw diesel generator fuel is currently a bit pricier than gasoline, however, it is much more stable and the fluctuations are less severe. With a diesel generator, you also burn less fuel. They run more effectively than gas, so the larger cost of gas is quickly offset by the "mileage" an individual while running one.
Price has to be in this particular conversation too. It is far too often that a person will not consider this most basic of needs when to look at selection for a generator.
