This commercial 3D modeller seems to be the best on the market when it comes to organic models. The price of almost US$500 may be a bit steep for some, but it looks like it would be worth it to me.

trueSpace 7.6 is now free for all uses.
A very easy to use 3D modeling program from Google. It focuses on architectural models, and is not recommended for organic models. The free version only saves the 3D models in a format native to SketchUp, but the Pro version allows saving in common 3D file formats. It is however, quite easy to find converters to convert the SketchUp format to a more common 3D file format.
