So where's the scam? You can find the scam by going to any big box electronics retailer and looking in the cable aisle. There you will find HDMI cables priced as low as $25 or $30 (if not, definitely head toward your local discount retailer for better prices). But you will also find HDMI cables priced above $100. And if you talk to a sales person, he will definitely be steering you toward the most expensive model. That is the scam. You can understand the scam if you understand how an HDMI cable works and what it does.
That being said, there is one two things you do need to be aware of when purchasing an HDMI cable. First, you have to get the right length. If the cable isn't long enough, it won't reach to the HDTV. Second, HDMI cables have version numbers. For example, version 1.3 of HDMI can carry twice as much data as prior versions. If you buy a high-end HDTV that needs a version 1.3 cable, you need to make sure that the cable you buy supports version 1.3. Otherwise you are not getting everything that the equipment has to offer. In that case buy the cheapest version 1.3 cable available, and it will work fine.
