Just to give this awesome tool some heads-up... Blender seems to get all the attention, but for most modeling related tasks Wings3D is actually much superior to Blender (and Bmesh seems to be still a long way off).
So check it out, especially if you are new to 3D modeling, as it is also much easier to learn then Blender (even though it has gotten better with 2.5).
