I just ordered my copy! It is out of print, but there are a few copies on Amazon and Ebay. I got mine from Ebay for $175. That is a lot of money for a book, but:
1. It seems to be the holy grail for Luftwaffe modelers, of which I am one
2. The other copies are going for about $235 to $250, so this is a bargain for a book in "perfect fine condition" as the listing said.
It is being shipped right now and I should have it sometime this coming week. I can't wait!!!
