I had not heard that they were that cheap.  I had heard that there were small ones for under $5,000 which is still cheap for what they do.  I've seen the output of one of these and it is indeed fascinating.  They 
definitely have possibilities in creating models from drawings which could be particularly useful in educating blind kids.

Best regards,
