Here’s a very interesting article about two products, well one product under two different names, which someone is selling for money and which is available (or are available?) for absolutely FREE at Blender.org

If you are interested in 3D, DON’T buy these products. 3DMagix and IllusionMage are nothing more than Blender under a different name. And Blender, my friends, is as free as free can be.
