Price: $2000 plus shipping and insurance (estimated about $300 – transmitter is heavy) or can pick up in Brooklyn

Note: The Ascension system can interface with MaxMSP via the serial object. It provides very fast and very accurate 6-DOF tracking (x/y/z and three axes of rotation). I have used it in several projects, and it works extremely well. It can be used as for conducting, as multiple 3D joysticks, for motion capture and much more. – Eric Singer
