Actually, I don't use Blender for modeling, but I think too that GUI Blender is "non-conventional" but not difficult.

For me is like WordPerfect 5.1. When finally you learned all the keys and combinations, it was powerful and quiclky. (Ok....the 3 first months I wanted to fire to WP51 developers) :-)

I didn't know that Blender didn't import the OBJ files properly.

I remember that someone in the forum created a script for import the MoI models in LWO format, but I haven't try those script in Blender 2.5.
