Hello folks! I don't own a Domino yet but I will have one for Christmas (or sooner). My question is about Woodpeckers' Newest "One Time Tool," the Offset Base System and track for the Domino DF500. Since I don't own a Domino yet, I don't know enough about its operation to know just how useful this OTT or the other DF500 package of depth-stop shims will really add value. I can say that every danged OTT that I have bought from woodpeckers has been incredible and I have always regretted passing on OTT's that piqued my interest but that I couldn't justify given the costs. So, the question is, would this be useful add-on? Thanks, Rich
