Reading here the suggestions, they seem to lean to: never go under 8in for the (parallelogram) jointer & get the widest possible. For planers also get the widest budget will allow. Felder when possible, jointer/planer combo is OK. MY questions: (1)Are J/P combos parallelogram? If not should I only look at separate s if there is room?(2)with a budget around $6500 & plenty of 220 outlets are Grizzly machines with spiral cutterheads(G0609 12"x83" P.jointer $$2500) and (G0454Z 20" planer at $2500) a bad move? .How about the Grizzly G0634Xp 12in J/P combo at $2200? In my research Felder seems better but at $10,000. Powermatic & Jet seem same as Grizzly but +$. Express your wisdom , please. I do not want to buy something I am going to regret. Thank you
