Cheap Laptop

Hey everyone, I have a rig I built that I use to do all of my raiding and PvP. I am looking for a cheap laptop under $400. I know that isnt much, but I just need something to do my dailies, crafting and post auctions. I might do a dungeon here and there. So low- mid settings is fine.Reason behind this is I have my Desktop in my office and when I do my daily MMO crap I rather stay on the couch watching a flick while I knock dailies and farm mats. Any advice would great. Thanks
