I don't think there are big numbers being imported anymore, so it's not likely they're going to get a whole lot cheaper. $250-300 seemed to be about the lowest pre-panic prices, and $400 isn't a bad price for some specimens, especially in the current market. They will always be around though, too many of them in circulation to go away. Might get a bit cheaper but might not.
Wish I had bought several when I bought mine 8 years ago.
