Hi Tom,

> So if we could repeatably make plastic films of exact thickness, we could have cheap tight-tolerance capacitors? Does that follow?

Looked on Farnell just now for 100p, 1n0 and 10n caps at 1% tolerance.
There are 21 through-hole choices, mostly film and mica, a couple of
C0G/NPO.
How cheap is "cheap"..?
