i paid £330 all in for it with 2 gig worth of memory too
but this was in india where they are a bit priceier
i've seen them on the net for as low as about £240 and then they go up to about the £280-90 mark form more reputable outlets like amazon etc

i've got a black one but there are some good prices there, even duty free they were upwards of about the £220 mark and i bought mine from sony with a 5 year warranty so i'm willing to pay the extra for that
