I first heard of Monoprice from one of the podcast I subscribe to.  They are a website that sells incredibly affordable cables and other AV/networking accessories.  I was recently in the market for an HDMI cable and didn't feel like paying the Best Buy or Radio Shack prices.  I bought 2 6' red HDMI cables for about $7 on their site.  One cool thing about their site is you can buy cables in any color you want.  I'm very happy with the cables I bought so check out their site if you needs some inexpensive HDMI cables.
