Rhino is less than $800 if bought from a reseller online...

Also, someone mentioned the need to use plugins to accomplish advanced tasks in Rhino. That's not true. Many plugins (especially the jewelry-related ones) are not really adding new features as much as they are just wrapping up Rhino functions into a different interface. A lot of scripts are out there for free which can handle a lot of that function too. The most common plugins which "really" add new features are Tsplines, the various CAM plugins, the various render engines, Grasshopper, etc. And you can't factor those into the equation of Rhino vs. MoI because MoI has no equivalent. So it's only fair to look at the price in terms of whether that software fulfills your needs...
