The machine cost around $40,000 (that was the only number I could get the school to tell me about it). I think the actual work comes down to like $200 an hour of machine use, but we could charge much less. We have the MAXUM model, which is the largest available. It is 24x20x24 inches, I believe the it is accurate the to 5/1000 of an inch, but Im not 100% sure. There are some VERY complex and accurate examples on their site.
