$5 plus shipping and handling. If it works, you are in luck. When ordering from Amazon, I tend to pay attention to user feedback. I never heard of Bargaincell. If you don't mind iterating several times until you get an acceptable cable, this one's for you!
Regardless of where you buy, make sure the cable has a dock connector to attach to your device. The Apple A/V cable also included a USB connector for attaching to a wall power supply.
