I had the link for the OBJ im/export script for Blender, but it seems like the site is down. However, the author wrote it to create morphs for Poser, so it should work pretty well with Poser. I really like Blender, and if you work through Tutorials or a good book, the UI ain't that bad. It is a little frightening at first since it doesn't give you any hints, but since I got the basics I can work a lot faster in Blender than in C4D. Give it a shot, it's free, it's cross-platform and it has a decent list of features.
