...GM is the easiest, but you cant want much from it

I do agree that it is the easiest but I think that if used in the right hands you can expect ALOT...Though it may take many, many years of experience to make it that good.

Blender is good to begin with (heck, almost every single other 3D modeling software is PAID for, while Blender is absolutely free)

 

Blender may be a good thing to start with but I find Anim8or is a realy good free 3D program. I've never used blender before so it might be better but i realy think anim8or is great for beginners.
