Probably not much help but i just took delivery of a Grizzly G0858 (8" Parallelogram Spiral Cutter Jointer) and the machine really doesn't vibrate much at all. My only problem was that the inserts on the spiral cutter head all needed to be removed and cleaned along with the cutter head itself. I was getting some visible lines lengthwise when jointing. After cleaning and reinstalling the inserts, it cuts VERY smooth! Vibration of the machine itself is very minimal, i'd assume yours should run the same. My old Delta 37-207 vibrated a bit but still made very clean cuts. Good luck with your new machine!
