if you want to make your own models you might want to try Rhino. It doesnt have an interface like Bryce but its still easy to learn and the Rhino forum here has may talented people and lots of tuts. You can get it here for $570 I think or if you're a student--or you could buy it for your favorite student :)-- its $180. The student version is the same as the other so theres no limitations. There is also a demo @ Rhino3d.com with no limitations except ou can only save 25 times. you can still use it after that but you cant save anything...
