www.monoprice.com - The 50 foot cable is perfect, and the price is great.
Do some searching, you will hear more than a few people singing the praises of Monoprice. I just brought in a 50' HDMI cable from them and hooked it up to my PS3 to a Sharp 52" LCD - the LCD is only 6" from the PS3, but I used the 50' cable for grins and giggles...
Perfect 1080p/24 without hitch.
This is just the way they work, and spending more to get the same thing doesn't make much sense, yet if I
was going to do this, I would go to Blue Jeans in a second over other companies.
Just for fun I'm going to use an HDMI extender with a 35' HDMI cable with the 50' cable to see if it works.
