Dreamcast S-video quality

I need to buy an S-video cable for my Dreamcast and was wondering if the quality varies from brand to brand? I see so many on ebay with out boxes and wonder if they are some cheap brand.

The S-Video AV cable I bought from ElectricQuarter on ebay works great!
The cord is even white to match the Dreamcast case. The Saturn S-Video AV cable I bought from them works great, too (they even threw in a free replacement battery for the Saturn).

I have one from lik-sang and it works great.
