I use the Porter Cable 24” Omni Jig. I’ve had it for about six years, so it’s not their newest system. I’ve been interested in buying the new system. It looks pretty simple to set up and use. Mine is an exercise in re-learning every single time I use it. The new one looks much more user friendly. When I was looking for jigs, I almost bought the Leigh, and wish I would have got it instead. The Leigh makes adjustable dovetails and is fairly straight forward to set up and use. The P/C makes standard width pins as well as variable spaced pins if you buy the additional template, but it’s not quite as adjustable as the Leigh. I have the template (as well as the sliding dovetail template) and have used it a couple times. It does OK.
Out of all of them, I’d still stick with the new P/C omni or Leigh. Don’t screw around with those little cheap jigs though. They’re a waste of money.
