The PE ship can be bought at Sky Hook Models
for 50.00 plus shipping. I do not know about it being rare or not as it has been up for sale for a couple of years now. It is also not licensed as far as I know.
It is a pretty neat little item and if I had more skills at model making and painting I would slap this guy together. There is not much too it as the body is one piece and all the winds are seperate pieces that need to be glued together. The stickers are really well done and the overall sculpt of the item is really true to the show.
I would agree with what everyone else has been saying in that the Zoidberg and Bender models were never produced. If they have I never seen them.
