Hi Dan!?
My apologies for the late addition to this conversation. I recently received my KF700SP, and had a similar situation as you (second guessing all-analog), and here are my notes:
For the digital flip stops for crosscutting, I determined it would be most cost effective to use Brian Lamb's flip stops on my analog fence. That being said, I've been happy with my analog flip stops and can regularly nail measurements to better than 0.5mm (that's less than 1/32").?
For the rip fence, the mechanically driven rip fence can not be retrofitted. That being said, if you're just looking for the DRO, you can order the DRO parts from Felder and install them yourself. The Felder service department was really helpful in terms of helping my identify what parts I'd need to order to accomplish this. After using my saw for a year though, I'm finding that I'm happy with the analog fence.?
Again, for the work I'm performing, hitting measurements within 1/64"+/- is plenty accurate, and I have work-arounds for work requiring accuracy better than 1/64". It really depends on how you plan on using your machine. Hope this helps!?
