Not sure what Kodrakon is -- might it be a Kodak trade name in central Europe?
If you are asking about prices for the Ektra, they are very high. Kodak made very few of them, and because they were a very ambitious and high quality camera, they are highly sought after. Even the bits and pieces fetch large sums of money.
On the other hand, the various Arguses, the C 3, C44 etc are quite cheap. The C 3 was the best selling camera in history at least up til the 80's, and since there isn't much to distinguish a working one from a non working one -- more wheezing from the functional one -- there are plenty to meet demand. The telephotos and semiwide angles are less common, but still not expensive. Those for the the later ones were made in Germany.
It occurs to me I forgot one other high quality american 35mm, which was the Bell and Howell Photon, a complex and potentially world class camera which didn't sell because it cost more than some cars, and used T stops rather than F stops (more accurate, and used in the movie industry -- remember Bell and Howell was largely a movie camera/projector company), but unfamiliar to the public. Lenses for the Photon were not made in America, though. They were produced by Cooke or Taylor Hobson in England. Some ended up being modified for Leica mounts by an outfit in Italy, I think, after the Photon tanked. (The Photon is also an expensive and sought after collectible. The only one I've ever seen was on display at Caruso's Cameras in Greenwich CT, and was stolen. A nice way of showing appreciation for letting the public view the manager's collection.
