"I have a license of MODO 801 and I have Sub-d-modeling as a part of my design process. I really like to do the initial modeling in MODO. I have spent about 4 months now in MoDo and I feel that its great for the early design phase - Push/pull polygons to create a base-mesh and to play around try out different concepts. But as this part is completed I prefer going to a Nurbs modeler to finalize things."

Blindfoldjump - Maybe you have looked at this already ... ?

I've used the SolidWorks version of this plugin. It works fairly well, however, it is not intended for very high number of polys.
