If you buy Carrara Studio right now, you get Amapi 5 and all the plugins for Carrara. Carrara is more of an all around 3D package, beautiful renders, animation, great texturing, scene building, and a lot more. Amapi is really just a modeller, but it is a great tool and together it and Carrara are an unbeatable modeling/rendering packaage. You would definately be pleased with upgrading to Carrara.
