This is the one I'm planning to purchase and have installed. They're on sale now; seems like a great deal. I've been researching generators for about the past 5 years. Now, just waiting to speak to the fire department to see if they will let me run it on propane, otherwise I need to connect it to my natural gas line after pg&e comes out to connect a meter. Also need to check with the health department to see where I can place it on my property. It's only 71db at 23 feet at full throttle, but the health department has codes (too) that need adhering to.God luck.
Best,
R.K.
