I still don't really understand how to gauge specs on different units for my application.

For instance the Structure Sensor has an accuracy of 0.5mm @ .3 meters for $380.
Meanwhile the Faro Freestyle 3D scanner also has 0.5mm accuracy and is $11,000.

I found a Structure Sensor on eBay for only $200 so I picked that up to try out. Is there a benefit to purchasing better software for the Structure Sensor rather than using Skanect?
