Are you planning on using a flat CNC platen or a friction feed gripper system like most vinyl plotters?
Different vinyl types require different depths, an intermediate vinyl is usually 3.2 mil and uses 210 grams of force for a clean cut without cutting the liner. Premiums - 2 mil - 140 gf. Make sure you have a micro adjustment feature that you can set and forget.
I have seen the roto-x-acto which is made by x-acto mounted to a cnc machine. I would be kinda wary cutting anything smaller than .75" or so. The vinyls require a really clean cut on the corners to weed cleanly. Using software that slows down into the corner will help out a lot.
I would suggest buying an adjustable head from a plotter repair / supplier. The last one I priced out... I think... was around 50 US. dollar. Build a clip in holder on your router settup and your set.
Another idea for anyone that self produces small graphics is to buy cutoffs of printable vinyl. Run it through your inkjet printer, clear coat it with UV stabilizer, cold laminate it and then hand contour cut. I use this method to make signs all the time.
