Graphics Software Tools

Where can I find cheap 3D graphic software tools. I see that 3ds, maya, alias all costs thousands of dollars. So, where can I find inexpensive graphics tools.

milkshape 3d is a cheap alternative not as sophisticated as 3ds or maya but that stuf aint all that any way (well it is but u have to make copromises).
