One tool/machine to level up a moderate shop

[Monochron]

This question has been asked many times before, so I will pose it in a slightly different way.

Say your team has a modest shop facility. You have most mid-range tools such as cordless drills, manual hand tools, calipers, jig saws, chop saws, drill press, band saw, grinders, and belt sanders. Basically, you can generally do small scale fabrication without a lot of precision. What is THE ONE tool/machine you would get to level up your shop?

I know the usual top two machines that get suggested but I want to ask, if you can only get one, what one should it be? Don't worry too much about price, anywhere from a couple hundred to a little over a thousand is reasonable.
