Although I paid more than what I see advertised in monoprice.com (recommended by Videodrome), I can speak from experience that my 50' DVI-D cable from cablesforless.com is awesome. It is, as my wife calls it, "a man's cable". This cable is like a garden hose and I have not noticed any problems whatsoever with the signal. The only drawback is that the cable is so friggin' heavy that I had to strap it down so it would not pull out of the connector (or take down my very light weight Oppo DVD player) on its own weight.
