I picked up one of these cables from a Goodwill for $0.50 but I couldn't get it to work on my older 32" 720p HDTV. I guess I should note that I have an RCA switch box that I was running through (so I can switch between my Blu-ray player, Wii, GameCube or PSX on that TV). There's probably something I needed to put in /boot/config.txt. I didn't really try very hard because it already works great with my HDMI cable.
