What also suprises me is how bad brand new props can be, despite

In my life I've purchased two brand new McCauley fixed pitch props.
Both were substantially out-of-balance as they came out of the box,
and both were fixed by a local prop shop. I am amazed the prop shop
(Maxwell) could do better given their comparatively crude tools. Must
just be skill & attention to detail.

This flys in the face of the "FAA certified parts are perfect" theory.
One would think after spending several thousand dollars on a piece of
forged aluminum that might cost 200 bucks in raw materials that the
remaining costs are for the manufacturer to deliver a high quality
product. The fact that a local prop shop with crud tools can balance
it better then the manufatcturer is laughable......... JMHO..

The same goes for the engine manufacturers. I put six new Millenium
cylinders on about a year and a half ago, all the pistons within 1 gram.
On a typical Continental they don't really care how much the pistons
weigh.
