I have a system of programs i use for my modeling. They area ll free, but the cost-money programs are better, I'm pretty sure. PM me for more info. In the meantime, you might want to ask... yes, Bino Maus. [;)] His models are so cool.
Take the links. DL both of them. That's my modeling system I use. If I can't model something in anim*tor that I can model in gs, then gs is there. But gs doesn't support certain modeling like spheres and certain material settings. The best would probably be to use 3dsmax.
http://www.blender.org/ that is the blender home site. you can download the program by going to the download section. There are many on-site tutorials for the program.
