Gamecube Digital A/V Out Cable

Hey, so I got a Gamecube that requires a digital A/V out cable. I didn't get any cables with it, so I got an analog cable and I meant to get a digital one, too, but... I can't find it? There are things that I think might be it, but none of them say "digital" anywhere, and I don't really know much about this type of stuff. The closest I've gotten is around $300...

Does anyone know where I can get a cheap digital A/V out cable for the Gamecube?

maybe you can get lucky and get one for 160$ on ebay.

sorry but component cables for the gamecube are very rare.

you are better off getting another gamecube that uses a regular composite cable. might be cheaper.

Does anyone know where I can find one? The only searches I can think of don't do any good...

@spotgame:

It's cheaper just to buy an original Wii and use the backwards compatibility with GameCube games. The component cables are readily available for 5 bucks.

Looks surprisingly good on my 58 inch TV
