Best "docking" cable for iPhone? (Audio connector + USB charging)
 

I am looking for a high-quality docking cable to charge and listen to music on my iPhone 4S in the car. The one I have now has a 30-pin dock connector that provides both audio out and USB charging, with a "Y" connector at the other end that provides an AUX plug and USB plug. Unfortunately, this cable is cheap and the cord frays within a few months of usage. I've gone through 3 of these cables, bought off eBay for less than $10 each, and it's annoying to have to replace them so often.

I have searched thoroughly online and haven't found any other more durable brands of this cable. Anyone know where I can buy one? It is mighty convenient to just have to plug in one connector, rather than trying to fumble with the headphone jack on the iPhone and a charger.

I'm a big fan of this cable: https://www.amazon.com/dp/B003SX0O34...9C8EYAPSWHFN1&

Bonus - it has controls in the DC plug.
