Found these on Amazon 2day for $24.99, 50% off the $49.99 list price. Worked out to $34.99 after shipping to 5000.
They have been cheaper on OzBargain before but can't find any in stock selling for less at the moment. They also come with a lifetime warranty ;)
Enjoy :)
Edit: Prices given are USD
I have a pair of these, decent sound for little money.
