I have been eyeing the belkin WeMo plugs for some time now, cheapest I have seen them was $59 for 2.  This will be $30 Australia for one, plus $10 in shipping.  But its going to be “open” in theory for development for Apps, so you don’t have to depend on Belkins apps to use it.  My 2 cents, Belkin is cheaper but not open, I wonder if this will change now.  I would stick with the Belkin myself.
