I stand corrected on the European version. Here is the web page on the M9 bayonets:

My prices were based on a two month period in early 2010 when I was looking to add an M9 to my collection. I saw several Phrobis Int'l marked M9s priced over $100 (between $125-175) that didn't sell at those prices. As in all things, timing and opportunity can make a big difference.
