I know nothing about PS and xbox, but I ask myself why do you need specifically AWG30? would AWG28 not do? (this is extremely easy to come by, as almost all computer cables are awg28 - old IDE cables are awg28 and are usually made up of 40 individualy sleeved wires...)
maybe awg28 won't do (admittedly IDE cables are only about 2 feet long) - it was just a thought
