I'm reminded of an incident a few years back when Monster sent a cease and desist letter to Blue Jeans Cable. The CEO wrote them a response that was pretty well publicized: http://gizmodo.com/380055/blue-jeans-cable-calls-bs-on-monst...

I bought some cables from http://www.bluejeanscable.com/ a few months later. I needed to make a few longer than normal runs, and they had reasonable prices and were direct about the capabilities of their different products outside of spec.
