Need help with HDMI or DVI cable

[BRANDONH]

Hello all. I currently have a new home under construction and I am prewiring the living room for home theater. I will be hanging a plasma on one wall with my component rack on a side wall. I am running all the wiring in wall so I don't have cables running all over the place and I need to find an HDMI or DVI cable before the drywall goes up. Hope you guys can help. It needs to be 20-30 ft long in order to reach and I refuse to pay Monster prices. Are there any budget places for these cables out there? I found more sites offering longer lengths of DVI cables but not HDMI. I thought HDMI did better over longer runs? Any advantage to using either type cable? I would rather use HDMI as I believe that will be the future standard. But I could always use adapters too. Thanks for the help.

I'm not going to push you one way or the other here is a link explaining HDMI technology.
It sounds like to me it would be best do go with HDMI but it is new technology.
