I was bidding on one from Z1 and got an email from this other guy saying he has one for sale too. I think the user id was something whitefairlady... I know about his auctions but his rating wasn't all that great and it was private to boot. Anyway, the email address that he sent it from is amzperformance.com or something like that. I was temped but ended up deciding that I don't really need the J-spec right now...
