I tried David a while ago, it gives good results. But the scanning process takes time, and you get only one angle from one direction, so getting a complete human scanned could proove to be a but tricky.

The results are too high-poly for rigging. But some modeling packages have tools for doing a retopology quite fast, for example Silo's topology brush and it's Polygon creation tool.

You don't need the pro version for first scans, and a line laser for housebulding isn't that expensive. If you want to scan a whole body, to my experience a ultra-fine line ien't really important. 

A ship in port is safe; but that is not what ships are built for.
