What do you guys think would be the better machine for the $$. I am looking at powermatic 60 (green version) that appears to be in very nice condition for $600-700, or do you think that I would be better off spending an extra $300 to buy a new Grizzly G0656? I currently have a 1950's Delta 6" jointer that has served me well, but is just not large enough. Any help would be appreciated.
