I bought a few Dells and Acers, all less than £400 each, over last christmas, Buel, some online and some from Tesco. Everyone seems quite happy with them, although it has only been three months. They're not gaming laptops, so if it's a decent game playing laptop you're looking £400 probably isn't going to cut it. All of the laptops I bought had dual core processors, 3 - 4 GB of RAM, were wireless enabled and had 250 - 320 GB hard drives. Their model numbers have escaped me at the moment, but you should be able to get something similar for the money, check out the respective websites.
