Not likely. If PS3 breaks within warrantee then I might replace it with Slim, but I won't be paying for one. If Phat breaks I'll either buy 2nd hand replacement or not buy anything.
So for this poll - No.
a) $0 like I said I'll only get one as a replacement if my phat keels over within warrantee and can't be repaired (not likely).
b) If I was going to buy new I'd expect to pay NZD $520 (USD $349, though I expect it to be $299 in the US)
c) 2nd
