I guess many people believe that this book (review here: http://www.landships.freeservers.com/radpanzer.htm) costs a lot now and there's nothing strange in it if you look only at the prices at Amazon. A few weeks ago I found this book at normal price at www.zinnfigur.com but I didn't want to reveal this information until I check if this book is indeed available there (sometimes information on the webside is wrong). But as I received the book yesterday, I can recommend you buying it there. The site is constructed in the way that giving a direct link is impossible. So to find this book you need to type author's last name (Kaufhold-Roll) in the search field (top left corner) and voila.
By the way, the book is really good and I can say it although I know German only a little. But it's not a big problem, I will translate it using a German-Polish dictionary :)
If I were you I would order it from www.zinnfigur.com . I don't think this book can be found cheaper than 19,80 EUR (price from Zinnfigur). Of course there will be some shipping costs, but comparing it with prices from Amazon and other Internet sellers it will be still way cheaper (look at the insane price at amazon.com: $677.51 + $3.99 shipping).
