I bought mine a couple of years ago in the US for $350 and with the dollar the way it is you are getting a bargin if they are only now 400 or less. I can tell you that your buying a first class pistol I have had a number of them over the years. Not so long ago they where the European bodyguards pistol of choice.
Oh, in France they retail for about 585 euros ($740'ish)!
As was said earlier, it all depends an where you live. I'm in California and I paid almost $500. plus fees. Get it whatever it costs, it's absolutely worth it. The 75B is an outstanding pistol and you won't regret it.
