If JessEm's past products are a guide, this new mitre gauge should be a keeper. I was looking at the Incra Incra® Miter 1000SE Gauge 86N60.01, but did not pull the trigger. The JessEm's is similar to Incra 3000SE in price.
This feature "Easy indexing allows for adjustments at 0, 15, 22.5, 30 and 45 degrees" would meet all my foreseable needs. For all other angles, I have the Kapex.
