I also started with POVRay, but when I got into Poser and needed a polygon modeller I downloaded Anim8or. I don't remember why exactly, but I think it was featured in a tutorial on how to make morphs. Since then I've tried Marble Clay, Blender, Wings, trueSpace, Cinema 4D, Amorphium, Silo and gMax, but - this is the important bit - because I already had a tool I sort-of knew how to use, I didn't give any of these enough time to really learn what they could do. Fortunately all were either free or demo versions so I haven't lost anything by it, but inertia is a powerful force in this, as in a lot of marketing situations. "Learning a new modeller" is not a task I have any interest in, so once I'd learned enough of my first one I concentrated on modelling itself, which IS interesting to me. As a result, I'm probably stuck using a very limited toolset, and I would benefit from switching at some point. But my mind doesn't work that way. Given the choice between learning (boring) and making (fun) I choose fun every time. So sue me. :)
