I have been runnig the Dewalt 13 for a number of years and have recently been planing a lot of rough lumber. I switched to the spiral cutter head $275 I think from eBay and it has made all the difference. I run have hickory, white oak, black walnut, cherry and sycamore thru it and it is still on the first side of the cutters. It gnaws right thru a 12" sycamore no problem
