I'm suprised no one has brought up Monoprice.com yet. I've been using them for years with no issues at all. Great cable. My entire theater is wired with these:
[Link: monoprice.com]Yes. $4.00 each is the real price. I have the Pioneer Elite Pro151 Plasma TV and Pioneer Elite Receiver and Blue-Ray player. I care what my picture looks like and I have compared them to the $100 cables in my home and there is no difference in picture or sound.
Everything else I have ordered from them - component video, DVI, and speaker cable - has been great quality as well. I highly recommend! (and I don't work for them either!)
