If you are going to model things, that is inorganic objects such as cars, radios, boats, spacehips, airplanes, then Rhino is your choice. If you are going for organics like beasts and birds and humanoids and fishes and such, then you will probably want to try Silo, or one of the other Polygon modelers. Check out Teyon's work in the modeling forum. I understand he is using Silo and Wings3D for most of his stuff these days.
