I was talking about the Makerbot Replicator and 3D printing when someone
asked me if I knew of companies that produce similarly affordable 3D
scanners. I couldn't think of any, but does anyone have suggestions?

Autodesk's 123D Catch does an acceptable job for a lot of applications.
 It's a free program.  Brian Harper has been doing some really good work
with it: http://www.theopencrowdproject.com/

From 2010

Thanks Brad.  I've been using 123D Catch with some pretty good results and
I'm getting close with figuring out how to run Reconstructme on the
computers I have - 3D scanning with an Xbox Kinect - although the quality
of the scans doesn't seem to be there yet with Reconstructme.

Anyway, earlier this year, I experimented a little bit with Makerscanner -
http://www.makerscanner.com/  I never had great results with it, but I also
didn't spend too much time experimenting with it, so it might be worth
looking into.  Basically its a system that allows you to laser scan with a
line laser and a webcam.
