Dang I did searches everywhere, and as you state nothing. The best bet as I am sure you know is eBay, and keep an eye on auctions that have multiple audiobooks since a lot of times they don’t list what the individual Destroyer titles are, they let the pictures do the talking. Also if you have yet to do so do a “Want It Now” listing on eBay it can get good results. Just make sure if someone contacts you saying they have one to sell check out their eBay name on Google first see if they are a rip-off artist. There has been a few cases of individuals trying to say they have something, but don’t have a camera or scanner asking for a money order as payment. I will keep searching to see what I might find.
