This should really be part and parcel with the bench unit. Why it's a separate buy is a little confusing to me since I'm unsure why you'd want the bench jointer capability without an angle stop. For less than $200 it's possible to convert the HL-850 planer into a bona fide jointer. Wow, that's impressive.Having a field jointer is beyond convenient, it's a gift from the tool gods atop Mt. Olympus.
