Cool, the bed looks nice. Most of the stuff I cut is fairly advanced stuff. I'm in the pattern making trade and our bread and butter is aerospace stuff so the castings we make are wild. Yes there is more power under the hood of Mastercam then Mecsoft visual mill but then again it costs 3X as much. You get what you pay for. But if you are using Rhino on a daily basis I would highly recommend staying with that and getting the CAM package for it. In this manner you would only be learning the interface to the CAM side of things. If you went with Alibre CAM or even VisualMill you would have to learn and become proficient at the CAD side before you could really make good uses of the CAM. No matter what system you were to chose you can always import a model in to machine it. So if you find Alibre, Mastercam,Moi3d,Solidworks... or any other system you like to design with you can always export the model and import it into Rhino if you start with that. Now as far as mid grade CAM systems are concerned I really feel Mecsoft system, weather plugin or Visual Mill is one of the best. I know people that use BobCad and don't like it at all, there are others that will swear by it. I've done some tests with BobCad and Mecsoft on large models. Mecsoft was a clear winner on tool path generation when it comes to speed. It took 10 minutes to generate a huge tool path with Mecsoft and over an hour with BobCad. That was on the same machine, same file, same programming stepdowns.
So If money is tight go with the Mecsoft plugin for Rhino, I have a friend that uses that on his router and he likes it. He's not a professional programmer or anything he just does it for hobby, so when he is having trouble programming something I go over to help out. The cool thing is that even though I don't know Rhino, I know the CAM system because it's the same as mine in Alibre so I can tell him what todo. Any way, I hope this helps some. I know it's always a tough decision on what CAD or CAM system to chose when your shelling out $$ for it but I think you will be pleased with Mecsoft, it's fairly easy to adapt to if you've been programming in Mastercam.
