I recently bought a Panasonic Full-HD (1080p) LCD TV to which I wanted to connect my existing Pana HDD/DVD recorder. Clearly, HDMI was the way to go, but I didn't want to spend a fortune on a cable that might deliver a performance only marginally better than one costing a lot less. So, having seen the previous reviews of the Pro Gold HDMI cable I decided to invest in one. And boy, am I pleased with the results.
Watching TV using the HDD recorder's Freeview tuner produces very good results, and in general picture quality is infinitely better than when watching through the TV's own tuner, with some broadcasts approaching near-HD quality (my TV has a Freesat tuner which enables me to receive BBC / ITV HD channels, so it's easy to make the comparison).
I really don't know very much about HDMI cables, and cannot compare one with another, but commonsense would suggest that if a particular brand of cable comes highly recommended by a bunch of other people, as the Pro Gold does, it's worth giving it a go. I did just that, and I am delighted with my choice. Buy one: you won't regret it.
