There's ten billion on eBay and Amazon. Avoid the dead cheap ones which are poorly made and won't last five minutes. Having dispensed with those, take your pick from any of the rest. And don't worry about the sound. Despite what some crazed lunatics will tell you, the good ones will all sound so nearly identical that there will never be a time when the sound-quality of the cable will be a limiting factor. When you've done what I have done, and lifted the lid on your highly-regarded HiFi amp only to find critical parts of the audio-chain are linked to each other by computer-grade ribbon-cables (which presumably do the job perfectly well), you'll realise that worrying about which interconnects are hanging out the ar$e-end is futile.
