I used to work for these guys in Holland, before they went bust and open-sourced the app.
Blender is a fantastic 3D modelling tool, with the learning curve of a cliff.
The next version should be getting a 3D Transform Gizmo and a few other nice features, but as a free tool, it rocks.

http://www.blender.org has more of a developer focus.
I’m currently working on an exporter path for Blender to Shockwave 3D ( via the XSI file format ), so that our car app can be used by colleges etc who can’t afford to purchase 3DS Max, Maya etc.
By the end of the year, Blender is going to be hot news, so definitely check it out now for a bit if you haven’t already!
