Do keep a watch on Evilbay. I got the Hornisse off of eBay about a 9 months ago for $45 and that includes shipping. I just caught it at the right time. The same thing is true with other Ma.K. kits. With a LOT of patients you will get one for a good price. I have 14 Ma. K. kits in my stash and I paid over $20 for only two of them, the Hornisse and the Falke.
As for the starshipmodeler store, I have purchased many items from them. Fast shipping and they are usually packaged well. You will get what you order from them. And if I remember correctly, shipping was very reasonable.
