I am in the market for a new jointer. I have an 8 powermatic with the helical head. I like the jointer but want a bigger one. I figure I might as well go to the 16. I recently purchased a minimax SC4 elite and am really liking the European machines. I already have a jet 20 planer with a helical head. My question is should I get a combo machine or just a stand alone jointer like the minimax f41 or felder a941? And should I get the helical cutterhead for the jointer or stuck with straight blades?
