I love Rhino, it's a very stable application. And it's very easy to get going with, and it imports and exports just about any 3D file formet you could need as well as full control over how many polygons the exported models will consist of. For the money nothing can beat it. It's got NURBS skills comparible to Power Animator which costs 15-20 times more. Anyone interested in Rhino should definately check it out and get the demo, it lets you save 25 times. I want to investigate OpenFX, I've heard great things about it,but is it stable? Is it a crash happy app? kaom
