Hmm, this is pretty much getting into impulse buy territory (for a 3D printer), and it even helps with my #1 problem justifying getting one which was that I haven't really learned any 3D modeling, by being capable of scanning (though I guess you could also do something similar with a Kinect). Could anyone with more insight into these things explain further why this is unique and whether there might be drawbacks? This almost seems too good to be true.

(for background, I just want a 3D printer to tinker with, and if it works at all for $100 I'll be satisfied - I might have as much fun building it as using it)
