Thanks for the link to the zSpace. I will check it out. (this fashion of starting a product name with a lower case letter, is certainly sticking around. But, I bet it is going to look silly another decade from now)
As I continue to do research, here are some force feedback devices I found. There is the Falcon by Novint. It is geared towards gamers, and only costs $250 USD. Another one, whic is geared towards 3-D computer modelers ,is the Touch by Geomagic. They also sell a lot of software packages. But, definitely in a different price category than the Falcon.
