As far as working, it doesnt matter. What you get when buying better cables is lack of external noises being injected into the cable (via onboard computers, etc.). Also a better built cable will also last longer, and will take abuse better (thicker jackets over the wire, thicker wire, etc.). So the cheaper cables will work, but you may have to replace them more often (nicks, hard bends, etc. will take out a cheaper cable). Good luck on your purchase.
