Goto accessories & you will see it at the top of the list.

Amazon are selling a rediculous price and the cheapest I can find is $30. No way am I paying $30 for a cable.

Tried:
OW site & called. Nil
JB Site. Nil
Harvey Norman site. Nil
MSY Site. Nil
IJK Site. NIL

This is doing my head in. If anyone is selling or know where I can get it any info would be appreciated.
