After using an Incra LS Positioner fence on my router table I decided I liked it so much I bought one for my table saw even though my table saw fence was as good as a standard fence gets.
Once set up properly, you can rip a two inch slice, set fence to three inches, cut a slice, move to five inches, cut a slice, move to ten inches, cut a slice and the lay the two inch, three inch and five inch pieces on top of the ten inch and it will be an exact fit.
Cut a piece one day to an exact size, go back a few days later, set the fence to the same size and it will be exactly the same size. No need to cut all your pieces at the same time.
The Incra table saw fence allows for different approaches when doing woodworking. Take for example ripping thin strips. Lots of people have different approaches and different jigs to make it safe, but the Incra fence is safest of all. Take a wide board, any width, rip it to a 1/32 marking on the fence. Subtract the kerf width and desired width of thin piece, as thin as 1/32 inch, and rip your thin piece off the wide board. Move the fence the same amount to make additional pieces.
There is a downside to the Incra table saw fence, and that is it takes up space on your table saw top, so you can no longer use the table saw for finishing work or piling it full of stuff.
