I seriously would not buy any of the X3's posted by any of the two sellers right now. The one you posted doesn't even use its correct name so who knows if they are selling the right thing and Amazon may not be able to help you if they sell you something else.
X3's are in America already, they will be posted to Amazon by Micca and others soon.
Oh, I know that is why I haven't made any moves. Emusic Ent. is an authorized dealer, also, so expect them to be posting it at a lower price and fulfilled by Amazon once they see no sales. They did the same thing when the E12 first hit Amazon and its at its regular price, now.
As for the name, yea, quite odd... but Emusic is legit.
