on eBay. Look for a merchant called EdgeCellular. I put in the minimum bid for $14.99 (Buy it now price is $17.99) and I let the auction expire. No one else bid on it so it was $14.99 plus shipping ($8.00) for me. I got it within a week.
He has several simultaneous auctions going on at the same time so you will likely find one that should expire within the next couple of hours.
Results may vary... :P
