If you are using "edge rule layout" or "mill rule" and are a commercial production framer, you will not be disappointed. Hema, Protool, Mafell, and Festool are all closely related in design and engineering as they have all had, and still share engineering from tooltechnicsystems. Many of the design engineers have worked with each of the companies.
If you use "line rule" and do much in the way of live edge or Asian designs you will find that the "slotting" configuration of more use, and/or the less expensive but very functional Ryobi, Hitachi, and Makita machines.
Hope that helped,
