So the first question you ask yourself; does an expensive digital cable make a difference? I'm sure there are millions of people who will tell you that the more expensive the cable to better the picture. Well, being digital, providing the signal reaches the other end with the ones and zeros intact, it will make little difference.
This cable boasts gold connectors, silver solder and oxygen free copper cable. It has a thick insulation coating, with a mesh sort of sleeve around it. It works fine, I've got three of them, one for PS3, one for Sky HD, and one for an Onkyo amplifier. The PS3 works in full 1080p with 7.1 Linear PCM sound without any hesitation, so the cable itself conforms to all the specs.
My only complaint, and this will be the same for all heavily shielded cables, is the weight. It does feel like it might fall out the back without support, and the angle at which it can be comfortable bent is quite small, possibly about 200mm for a complete circle.
As with all audio / video / digital cables, buy the smallest length you need, and try not to run them in parallel with power cables.
