Mastercam and Gibbs are very expensive. If you have to ask you probably can't afford it. We have Gibbs Multi Task Machine (MTM) software and we have about $25,000 into it with the post processor. That is for one seat and doesn't include full 3, 4, or 5 axis contouring. You could easily add another 10 to 20 large to that number. You can take about $14,000 off that number for the MTM module and post.
