Wixey stuff is great - I have it on my DW 735 planer and on my Delta Unisaw - both the fence gauge and I use one of their angle gauges to measure the blade angle. For my router table, I set aside my old under-table Woodpecker's router lift and Incra fence and went with a Ready2Rout/Ready2Lift package from NextWave Automation - uses a couple of CNC motors and a zero plate, much like a CNC machine, but in a router table. You zero the bit height and fence and punch in on a touch screen the bit height and fence position. It's pricey (about $1k), but I am SURE I spent nearly that much on the Incra fence and lift. Now I know where the bit is in relation to the fence and how high it is EXACTLY... I never had the guts to try inlay before - now, measure the thickness and width of the inlay strip (digitally), zero the bit, punch location and depth of cut in to the touch screen, and off you go. I still make test cuts because it's a bit new to me, but it really does work. I did some box joints with the program and it did what I needed it to do - a little tight, though - you have to add some space for glue - it's that precise...
Tom, I also use the Sommerfeld jig, and it's great. Did a test door with it and it was fine. Am in the midst of demo on my kitchen - got the face frames done, countertop next week... hard to find time for with a 60-70 hour a week job.
To the point of the question - beware when you go digital - you can over-obsess on being precise and it isn't generally necessary. Things made out of wood are seldom precise - and even if they are, they change...
