ok, for ALL my cable needs, I stopped using big box stores (best buy, radio shack, etc.) They charge you about 500% what the cable cost. Take a look on http://www.monoprice.com
, their cables are solid, and are WAY more affordable than any chain store will ever be.
Every single one of my devices at home that needs a cable is being powered by the cables from monoprice. I dont know if they ship internationally, but give it a check.
