Bargaincell and SFCable sell Eforcity gold plated for 2-5 bucks a cable. Great picture quality on a 15ft. run, the longest i dared get from them. Both sellers come with good credentials.
If you want to be thorough i recommend RAMelectronics, a sponsor here. Waay above specs, great stuff.
Lately i use Amazon merchants for all my cable needs, very satisfied. Read buyer's product ratings, they are fairly accurate.
