After thinking about buying a cutter attachment, I decided it was worth trying this attachment and spending $30+ instead of $200+ on carpentry. The bit comes with three sizes of bearings, so you can connect #20, #10, and #0 biscuits by simply swapping out the included bearings. When used with my router table, cuts in pine were smooth and easy. At this point I see no way to buy a cookie joiner machine unless it was commercially made or simply required the best tooling available. Hope that helps.
