Just from personal experience I bought a cheap 3m HDMI cable for my xbox360/ps3 in the past and also bought a more expensive one (Category 2 "High Speed", Gold plated etc) for the two consoles. I found the more expensive one to be far superior in image quality than the cheap one.
Just beware if your buying a cheaper (Standard 1) it may not work at the distance you are looking at, as they aren't tested at these distances.

this might be of use to you.
