I must admit that I have been sucked into all the hype surrounding cables and wires a few times. I have however gotten a little wiser and now tend to search stuff out. Blujeans and Signal are guys who make decent cables at a fair price. I was snooping around some of the UK forums and everybody was talking about Black Sand Cables. I hunted them down and it turns out they are in my city. Small world. Anyway, I went and picked up some digital coax cables from them and they do nice work and are priced more then fair.

Black Sand Cable

From what the owner was telling me the web-site is new and is still a work in progress. I stopped in and it's not done but it has some good info so far. They have sold on word of mouth up till now.
