If you're looking for something that does modeling rendering and animation, then don't look at Hexagon.  Hexagon only does modeling and texturing.  You'd be better off trying out programs like Blender, Carrara, Cinema4D, LightWave, 3D Studio Max, XSI and Maya. Those programs offer everything you are looking for. If all you want to do is model, Hexagon is a solid program but it's interface isn't for everyone. I suggest trying out the demos of programs you are interested in and use your experience with that as a decision for purchasing.
