Bill,

What are you going to be doing?

I have an Incra 3000, and it's fine for what I do. I've got a short and long fence for it, with the stop system. I've never done anything tougher than an octagon shape. I also have the Cheaper Incra miter guage only (V27 maybe) that I use too when I need something a little more than the Delta, and I don't want to remove the fence off the 3000. I bought mine mostly for the fence system, which I love.

It looks like the Incra 5000 adds a sled to the 3000 system, with the same precision. I guess it depends.
