The only time I would suggest spending a bit more is over long runs (10m+) as HDMI isnt meant to run for massive distances unamplified. Saying that as the others have said it will generally either work or not work as its a digital signal. Make me laugh the amount of supposid AV experts that swear you can get a better picture with better cables. The whole point of digital is the picture being sent is encoded in a way that it will be exactly the same at the other end The only difference good cables will make is if it gets there or not, which is why you need better cables on longer runs, but this is usually only required if you have a projector.
