IIRC this is what a friend of mine has. Although the mfg. makes it look and sound simple it isn't. Accuracy isn't bad at 0.1mm(0.393"), but the issue lies in getting an accurate scan.
Pretty sure they don't tell you the scanner likes to see a flat neutral gray surface. Well it does, and not just any cheap hardware store spray can job will hack it.
I also know that while it will generate a point mesh you still need to manually fix/fill holes and anomalies in that mesh. If you don't you get a lousy part.
That may be fine for some low end 3D extruding printer, but won't hack it with a million dollar SLA rig. Or a Centroid 5 axis CNC(he has one of those too)
Know exactly what you want to do then research what's available. Check out your local technical college or university. They will have top line equipment most of the time.
In a nutshell: Like most things people want to sell you they only used a hand built, tweaked out rig showcasing what it can do best.
