Slight correction on the price of Rhino3D. Directly from www.rhino3d.com it costs $795, $195 with academic affiliation. DVDirect & SafeHarbor both carry the "retail" version of it for a little less... You can also find it even cheaper through academic software houses. Only reason I know so much about its price is because I just bought it recently, and let me say.... it ROCKS! There are also a few "workspaces" out there for it that make it look alot like A/W PA or SI if that is what you like.
