On a similar note, if a cylinder compression was low, would you rebuild
it,
or buy a new one?

It depends. Depending on the problem, and age of the cylinder, I'd probably
still buy new.

When you look at a new Millennium cylinder, and see where they have beefed
up the areas most likely to crack, it's an easy choice.
