I am really surprised at how difficult it is has been for you to find the Samurais you need. If I didn't have so many tourney players, the $1ks would be yours. Sorry.
As a side note, I got the Samurais in play last week and a number of my friends commented about it being a long time since we played with them and how much they like them. I got to tell the story about their trip to Australia and back about 5 times.
