Check Amazon Marketplace. I have been with Bluray since late 2006 and the in store mark up on HDMI cables is still insane. I buy all of mine on marketplace and they are just as good as the ones in the store and I have never paid more then $4 for an HDMI cable.

Quick question if your TV is so old does it even have an HDMI input?

Oh and I have to say as someone who lives in a small house I like flat screens for the simple reason that they take up less space. I mean before we had to have a big piece of furniture in our living room to hold our big screen TV, when we got a flatscreen we also got back two whole feet of living space in the living room. Even my mom who doesn't care what the picture looks like on most things loves that.
