I ordered a FET from Model Expo's shop on EvilBay literally the day before it was announced that Byrnes tools were back in production, and it arrived today. I had to make a minor (very minor!) adjustment to the fence by loosening the cap screw on top of the fence, but after that everything was as perfect as my ability to measure it could determine. Probably as accurate as I will ever need, to be sure. That said, thanks for the info you have posted. I may yet need to do some tweaking after it's shakedown cruise.
The miter gauge seems pretty sloppy in the T-slot, so I may yet have to do something about that, but I do think I'm going to really like the micro adjust feature on the fence. Going to make precise dadoes a snap.
