When I built out my home theater, I bought a bunch of Radio Shack "gold" cables and was quite happy with the results. Poking around Radio Shack's web site, they do have 3 foot lengths. Maybe your local store was out of stock. Now, if you want to spend more money, it seems that Radio Shack has added a new "FusionAV" line of premium cables that cost twice the price of the "gold" line. Or, you could just make your own.
