C4d is right up there with Max and Maya. However, if you're just learning, I'd say try a combination of Wings and Blender. Both free, both excellent programs to learn on.

Houdini has an edition that goes for 2000.

Lightwave is also an excellent program I have great respect for. Also used a lot in the industry.

Talent is God's gift to you. Using it is your gift to God.
