Want to use a non Festool router with the guide rails. Read the past threads on this subject. Have a few more questions. Debating between the guide stop by Festool $63 or the EZ SRK unit for $137. What are the pros and cons for each? Also, attaching the guidestop by Festool what routers would line up with their rod config? Any further attachment difficulties to the router? I know some will say to buy the Festool router but not possible now. Thanks for the help.
