HDMI cable scam used to fool in-store customers?

I agree with this article completely: For short runs (less than 15′), the cheapest HDMI cable will work just as well as the most expensive. For longer runs (30-50′), the higher quality cables are a must if you plan to run 1080i or 1080p resolutions.
