Reddit mentions of 3D Systems SENSE2 3D SCANNER (350470)

I'd consider it at £600 ($770) and almost certainly get one at £200. As for quality/accuracy I'd be looking for something accurate down to ~ 0.1mm-0.2mm, even 0.5mm-1mm would be useful as a guide in CAD but at a lower price point.

edit:

looks like some stuff exists in the price range, resolution and reviews aren't great tho.

A lot of 3D scanning is finding the right lighting conditions, the space to move around the subject, and how good is the software. There is probably a next generation coming but the 3D Sense from 3D Systems is a repackaged Realsense with their 3D Sense software. It helps that it has a forward diffuse lighting built-in. The Realsense short-throw has about 3mm resolution. It's a good starter to learn all the ins and outs, get output that isn't totally frustrating. The best thing is have a Windows Surface or touch screen laptop in a harness and walk around the subject with the scanner in one hand. The motion can't be too fast or track will be lost and it can't be too slow because the software will use up all the memory. Not too much of a risk for a learning experience and get useful working material. 3D Sense has some nice finish-up editing.
