I would buy a 360 at its current price if they would fix the reliability issues.
Wii - Bought at $250
PS3 - Bought at $350

Whatever i have too/$300AUS/$300AUS

Already got a Wii

PS3 - not going to buy, see below
PS3 slim - probably $300 Au
360 - That's a toughie. I would certainly prefer an extra Wii game to a 360, so certainly below $100. Probably $50 would entice me

PS3: $250 or less

I already own the others.

HD console : whenever i feel like buying one. 200$

Id buy then for what they are selling for at the time I feel I want one. The only one i dont have atm is the 360 and Id pay 100$ less for it than what a PS3 is worth so i can use that 100 to buy wireless.

I'd take his.

Already got Wii and 360 so for PS3 probably $200.

Wii-150
360-Will happen very soon.

I think the 360 and PS3 are fairly priced right now, but:

Xbox 360: £100 (all versions, there's nothing that appeals to me more in the Elite than in the basic, and I only want 2/3 games for it, two of which aren't out in Europe. I would probably sell if after I finish those two/three games).

Playstation 3: £200 (for whatever has backwards compatability. I would never spend more than this for a console. There aren't many games I want for this, either).

Wii: Nothing. Don't want one. If I was offered one for free, which I couldn't sell, I wouldn't want it.
