I've used and have access to the:
Next Engine HD Pro
They have this over at NextFAB right now:

I am a full member at NextFAB with access to just about everything.
So I can use the scanner within the $140 a month fee (some tools have extra fees but they are quite reasonable).
We scanned a couple of things.
NextFAB is talking about getting an arm, I've been thinking about building one open source.
I think the mistake to avoid is the idea that you'll end up just scanning everything and getting a perfect 3D point cloud to make into say an STL. There's often some things to fix up and obviously some things in a scan can be occluded.
They do have quite a collection of printed human heads however.
Tiny shrunken plastic and gypsum heads - feel free to tell Brandon I referred you he knows I jest.
I also have some of these scanners:

These work though the point cloud editing near completion is a bit of an issue.
That work is done with VRMesh Studio which has a licensing cost that is not insignificant.
This link might be of interest but there's some PR at work in it:

That's actually a slide show with quite a few slides showing the Next Engine performance versus competitors.
