I made a set of cables using the "commercial electric" branded ext cord. I used the 12 guage (yellow jacket) cord due to the distances I was running, and clipped the green wire. I think it cost me $50 for the set (ie for a 100ft cord), plus bananas.
I would go this route over Monster cable any day, but I'm not sure I would replace existing cables with it. I needed a new set because the Monster cable I had didn't fit the confuration of my room.
That said, I was very satisfied with the sound quality - I think is was an improvement over the Monster cables (though this was not a controlled/scientific comparison), but clearly not as good as my PS Audio Statements, nor my Totem bi-wires.
