Well, the only one that I can think of is the Krackenvogel, and to be honest, they are way too rare for someone to just give away, Looking at around $100-$150 just to get your hands on...
Other than that, there is the "Krote", which is like an ATST, "Hornisse", and the "Nutrocker".. But although more common, still pricy kits... I am no expert, but have a friend in the States that I keep an out for here in Japan, as he collects them..
Good luck in your search...
