I’m surprised to see that Rhino isn’t up there. It’s one of the most versatile NURBS modelers out there. I used Rhino quite a bit before EI had a modeler. Very stable, very fast and it’ll run well on practically any machine – even my Mac under Virtual PC!
I’m using Silo now that I’m not creating high-tolerenced models for manufacture but Rhino really should be on the list. In my opinion, it’s one of the best modelers out there.
Just my $0.02
