For static models, I use GameSpace Light.

gameSpace Light is not just a trial copy of gameSpace, but a functional package in its own right."

Now you can work on models using all the modeling and animation tools from gameSpace, and save models of up to 650 polygons so that you do not have to do everything in one go. "
If you want more than 650 polys then you can use the full version which is sold by TGC.
