I know of Ron's Jupiter 2 model.  He has done an absolutely amazing job on it as well as his animations.  I first saw his model over at Sci-Fi Meshes.  I believe he is using 3DS Max to create his model.

I had built the Jupiter 2 way in the past using Anim8or and again in Animation:Master.  Phil had seen my OBJ export from Animation:Master that I had uploaded to Sci-Fi Meshes.  He had asked if I could provide it in a different format for Poser. 

Since I had been working on a more accurate Season 1 J2 in Cinema 4D, I told Phil that I could work with this one and convert it to Poser.

You can see my J2 here www.scifi-meshes.com/forums/showthread.php  .  I was working from blueprints of the original models and props as well as screens shots and videos from season 1.

Phil has used a Poser J2 before, but was looking for something better so I agreed to work with him on this.  I am removing some of the extreme detail pieces for the Poser model (such as screws in the panel faces, etc.) that isn't really needed for a Poser model.  I also made the center control panel for him, which wasn't in Season 1.

The attached image is of the Electrodata B205 console that is used on the Jupiter 2.  The top render was done in C4D and the bottom render is the Poser version.  I have provide Phil with the textures so he can apply them to the model in Poser.  This has been another great learning experience for me in converting C4D models to another format.

As I mentioned earlier, I really don't use Poser all that much so I wasn't really aware of any other Jupiter 2 Poser models out there. 

Oh well, this is something that I really enjoy doing as a hobby when I am done work.
