At what price would you buy a Wii/Xbox 360/PS3?

[tabsina]

prices in AU$
wii - $400 because thats how much i paid for it
360 - $200-250 (250 if fable 2 is 360 exclusive, 200 if it goes to pc eventually)
ps3 - $150-200 (because it has low value to me personally, so why would i pay 700 or whatever it is right now for it)
