    This has got to be the quietest generator ever! It was a little more expensive than the PSTF8500 model but it was well worth it. This is a heavy duty machine!

    Bought this two years ago and just getting around to the review. I use this Genny to run my camp house at the deer lease. It is a bit overkill for my purposes but has performed flawlessly coming up on 400hrs over 8 months of use. I usually run it ~ 30hrs per weekend. just make sure you change your oil on schedule and check it every 8hrs of use or so.
