"Or apply your face to your own mesh and UV layout using the FaceGen Customizer."

I think that just applies a texture. Which is a good and useful thing, but most people who buy Facegen want to re-create a specific face. Celebrities and other digital clones. For that, you need to reshape the mesh.

If you're good enough at modeling to get a likeness in an original mesh, you can just take V3 or M3 into your modeling program and reshape their faces. Without having the hassle of trying to fit the Facegen mesh to the unimesh neck.

And that price is just for one module of Facegen. You'll need both the customizer and the modeller to do what the Face Room does. They are about $500 each, hence the $1,000 price tag quoted. If you want a license that allows you to redistribute, it's another $1,000.
