Post in the 1stGen forum, and likely someone will know where to find one. I havent been outside the 1stGen and 911 forums for over a month, and many are just like me in that regard.
It's supposedly a discontinued item. I know a guy locally who had one on ebay, and I never got around to bidding on it. I can try to get ahold of him and see if he still has it.
ALso try 1stGen.org
