Rhino 3D is the best that I have used, it has a lot of bang for the buck. Can be used to model, morph, & render. The newest version 1.1 even has a polygon reduction tool that is out of this world. Amorphium is good, but not for "real" modeling :) -Trav (P.S. If you want to see what rhino is capable of, take a look at the Rhino forum here, we have people who are making photo-real stuff with only a month of using the program)
