I don't know about the Grizzly 6" jointer your are interested in, but love my Grizzly 8" jointer, except I wish I had a 12" sometimes...

I seem to remember that Grizzly used to provide references to owners of their tools, so prospective buyers could call Grizzly owners of a given tool for a reference. Perhaps this is still done? You might Call Grizzly and ask...

Just a thought. Hopefully some owners of the jointer you are interested in will chime up!
