Welcome to the site, Poppop. I've got a Grizzly 6" jointer, too and have been happy with it for most work. If you want to graduate to an 8" jointer, the aforementioned Grizzly 0490 and Shopfox W1741 are the same jointer, manufactured in S.E. Asia. The parallelogram adjustments are reported to be excellent -- see Monty's review, mentioned above. As for your 6" unit, we have a good Buy and Sell Forum and a great network of folks going from here to there in the state to move equipment from one member selling to another member buying (I transported a 6" Grizzly from here in the mountains to Greensboro, where another member took it the rest of the way to its final home north of Durham).
Welcome to the site -- look to see your pics and your posts.
