I just got an XBox and was a bit dissapointed that all it came with was 3 RCA plugs for all of the A/V output. Ugh, cheapasses.
Obviously, Dolby Surround doesn't work with RCA left/right channel audio
I think I need to get the XBox AV Kit Thing which will give me optical outputs. Said optical audio will allow Dolby 5.1, which will make me smile. 
So my issue is, where do I get optical audio cabling and how much should it be? Honestly, I've never done anything with optical connections ever. It was about a month ago that I found out the optical audio "plugs" were just pieces of plastic to protect the internals.
Some searches yielded 10ft for $89 at ConUSSR. WTF? Please tell me this is not what I want. I know some of the newer computer speaker setups (and almost all of the new sound cards) have optical outputs, so people on here must know where to get the cables and how much they should be.
(I need ~15ft preferrably.)
Thanks
