I really can't spend money in a new laptop, I might have to stay with the current one for at least 2-3 months. So please leave suggestions please?

Also, here are some sites you can use to give me some suggestions:

1.http://www.bestbuy.com/
2.http://www.pcrichard.com/home.jsp
3.http://www.walmart.com/
4.If you know something better than those and trustful, you can use it.

Please hep me! :'(

($800 or less, that's my budget)
