I'm thinking $300, for anyone interested.
Shipping to Australia wouldn't be too horrendous, but we run on 240V not 110V, the plugs are different, and it's region-locked to NTSC or high-def output. (And I only have a standard-def PAL telly)
(And my girlfriend would kill me )
I believe the PS3 power supply is universal voltage-wise, so all you would need is an adapter plug to make it fit into your electrical socket. However, your TV would probably be a problem.
As for the girlfriend.. chloroform?
