At GeoSLAM (joint venture with CSIRO) we sell scanners and software based on the Zebedee (ZEB1) and a mechanically rotating version (the ZEB-REVO [1]).
The rotating version is easier to use (don't have to worry about nodding the head too fast or too little) while still having the same cost/speed advantages over terrestrial scanners.
