Monster Cable GCGL300 SV-10 GameCube S-Video A/V Cable (10 Feet)
Nice, but go with the component cable if you got the $$.
This product will give superior picture over the standard coax and composite cables.  If your TV has a S-Video input, but no compent input, you won't be disappointed with these.  Try comparing the pictures by using the standard cables and then the S-Video cable.  You'll really notice the difference (the colors will be more vibrant and the image sharper). <br /> <br />If you want the ultimate in picture clarity, get the component cables though.  I don't think Monster Cable makes component for the GameCube (I wish they did), but you'll be able to find other manufacturers that make them. <br /> <br />I only give this product 4 stars because I'm using component cables and it definitely makes a difference over the S-Video cable.  If Monster Cable ever came out with the GameCube version of the component cable, I'll most likely but it over my current ones.
