i am using two $30 35' HDMI cables in my family room. One is for a DirecTv HR21 receiver going to my Samsung LCD. And the other is for my 400 disc sony dvd player going to the tv. The receiver and dvd player are both located in the basement under the stairs. I have no issues at all using these cheap cables.
Now when I add a Bluray player, I might have to rethink this situation. But for these 1080i sources, I'm glad that I didnt waste my money on more expensive cables.
i bought them from www.eforcity.com
