I have Both the Woodpeckers and TSO track saw guide systems and without question the TSO unit is far superior to Woodpecckers. Wooodpeckers system is just not as easy to use as TSOs. To attach to the track you need both a hex driver and a Phillips screw driver but with TSO if you have a GRS-16PE or GRS-16 you can connect to the track without any tools. Another problem is with Woodpeckers system you need to connect one or more short tracks together to make cuts over 20" and with the TSO system you use either a 30" or 50" track. Again changing without tools. I do not have any experience with the Festool system. I would definitely not recommend Woodpeckers system and wished that I would not have wasted my money on it!
