Thanks 50 Parsecs. I might start messing around in Wings as well. I have played with it a little bit and the interface is a bit - awkward - compared to the environments that I'm used to (mostly used a borrowed version of 3DS Max ten years ago when I first tried my hand at this).

But I do like how clean it looks.

The most difficult one by far has been Blender - I can't even figure out how to adjust its interface properly but with Metasequoia and Wings along with CB and Sculptris, Blender is on my back burner for now.
