Genuine Apple headset adapter on the cheap

Need an adapter and don't want to shell out big bucks to pick one up? Apparently Apple's own iPod Shuffle Sport Case includes an adapter that fits the bill --and iPhone's slender port -- perfectly. Of course, the value add here is that these fellas are all but discontinued, so if you are speedy, you can likely gank one on eBay for under a dollar plus shipping. But hurry up, when the sellers catch word, there is no doubt that price will skyrocket.
