just to let you know dude, $190 is pretty pricy for parts bought IN australia for these, that is garunteed from a local guy who you can go yell at if the arms don;t show up. the guy who buys them from someone in the states and the on-sells them.
160 is the going rate right now and i suspect it will drop further.
and generally when you cut out the middle man, you sell them for less than the middle man.
