Look in to BobCAD. You should be able to talk them down to about $800 for a seat of V23. There will be a learning curve, but the software is VERY powerful once you learn how to use it. Ignore the people that say the software sucks - they don't know how to learn new things. The interface IS different from any CAD/CAM package out there, and it likely is not worth it to you to learn the CAD side of it. But, you will be able to import your Rhino solids in to it, and CAM away with as many different machining strategies as you like. If you want me to show you a CAM file off of one of your own models, send me an STL and I can show you what it can do [send to mike(at)mcpii(dot)com].
