I picked up this model in brand new for a bit over £400 not so long ago and I've seen some of these for around 450 on here recently. It's a pretty good spec and I'm pretty happy with mine.
I just thought that I'd try to share it with others as I think that it's a pretty handy computer.
Granted it doesn't come with much in the way of software from PC world, but if you're instore, try asking what you can get for free also as in credit crunch times, they might be keen on making the deal stick.
