Not quite sure this should be in the for sale subforum as of the moment, but there is a bloke in Austria who is game to reproduce the GP kit. He needs at least 6 orders to get it going. From the looks of it, he has 3 written down. The link is below. If you dont have an account, let me know and I'll talk with the thread starter. I've been discussing the situation with him and offered to help when he needs it or for translation and such.
