Dwight, I spot check boards. I lack sufficiently sensitive instruments to measure actual thickness (even on a surface plate, it's the same for ENIG as hard gold with an 0.0001" indicator) but ENIG won't stand up to a few swipes with an ink eraser, whereas hard gold will stand up to it no problem.

Douglas's boards are good quality, but IMO their edge connector socket is inappropriate for DEC boards.
