So, say, an angel comes from Heavens and brings me a Darex E-90.

How well will it really work for me, in real life?

'Couldn't tell you, having not used one, but they come precious, even
used, and high prices at re-sale usually mean they're well-accepted.

I have looked at the manuals and specs, and they spec-out as being able
to do very precise re-grinding.

There's at least one on E-bay right now for under $2000, used.
