Mwave have genuine PS3 Controllers for $49.95 for black and $49.99 for blue and red. Shipping is $2.75 with "Mwave Priority Transit Cover". Total $52.70.
I know these could be bought for around this price from UK/Asia but Mwave will be quicker to deliver these.
I got mine cheaper from ozgameshop as you stated http://www.ozgameshop.com/ps3-accessories/official-sony-dual…
Was delivered within a week.
At Least with ozgameshop I know my order wont get cancelled after it has been accepted and paid for.
