I also have a Jointech fence and have posted digital files of the strips on this forum that work with it. Jointech went out of business shortly after the owner/president died, and the family couldn't keep it going. In many ways their incremental fence systems and other products were superior to the Incra fences, and they would have been stiff competition for Incra if the company and their innovation ideas had lasted longer. I still use my Jointech IPM-1 with my router table when I want precision fence positioning, but I have other ways of making dovetail and box joints that are as precise, but faster now.
If it helps you in determining a value for yours, I paid $249 for my IPM-1 when I bought it new, The IPM-2 (longer version) was about $70 more. Mine is very well made and will easily last me the rest of my woodworking days as well as whoever ends up with it in their shop after I'm gone.
The Clincher system is equally well made, but I never had any experience in actually using one. I think it was better suited for use on a table saw or large router table. My router table is smaller and the IPM-1 is well suited for it.
