GB:
I have owned an Incra 2000 (no longer available) for about 7 or 8 years. After the initial setup it has been absolutely dependable. Straight forward adjustable in one degree increments, and with a built-in screw adjustment repeatably adjustable in 1/2 deg increments. Its shortcoming is it swings in one direction only, which is why (I believe) it was replaced by the 3000.
I have never been disappointed in any Incra product; in addition to the 2000 I own the 5000 and the recently available i-Box jig.
Good luck,
