Sam:

I have an excellent set of M'toyo micrometers, 0-3", carbide faces, digital, read to a ten thousandth of an inch. You really don't need to spend that much.

If you were earning your bread as a machinist I'd say jump on it, but you aren't.

And the price difference will buy quite a few gallons of fuel.

Think about it.

Twins are slick, but Q40's quick.
