www.outpost.com Not sure if they sell it online. Fry's store if you have one around you. Don't go to the stereo department. Go to computers and look at the wiring you will find good low priced cables. Was just in the store today. It was selling for $80.00 for 250 feet.
Ebay has had it on there for cheap.
