One of the other guys from The MakerHive has dome some Skanect/Kinect scanning. I think it's one of the most viable options that's out there, unless you need dimensions and are doing engineering work that requires precision. I've been debating whether or not to add a Structure sensor to my arsenal, and in that quest I've looked up the Kinect options a few times.
Interestingly, the XBox (game) version of the Kinect is limited in what it can scan. I think it's an artificial limitation, but I believe that you can only do black and white scans and you can't use the game version for commercial work - they want you to buy the microsoft one for PCs.
Let us know how your adventure goes, I'm curious to hear about how it works for you!
