Ditto for me. I also bought a used Unisaw and needed some info. They
were exceptionally helpful. In general I never have problems with power
tool manufacturers, Home Depot, Loews, etc. that the other posters
complain about. My experience is quite the opposite: I'm often
surprised that "I can return this without the original package, without
a receipt, or 3 months later".

I'm not sure about these disgruntled customers. I'd really like to hear
the retailers side of the story. It's probably something like -- "This
guy has returned 75 items in the last 20 days."
