Small and light is expensive :/ the closest to your price range I could find is this one "lenovo IdeaPad S400 (59342932)" at 499.99 can be found at www.newegg.com/Product/Product.aspx?Item=N82E16834310635.

If you can put up with a normal size laptop "ASUS X53 Series X53E-RH31" can be found at http://www.newegg.com/Product/Product.aspx?Item=N82E16834230571 for 339.99.

I recently got an Acer Aspire 5749Z-4706. It's pretty respectable for a cheap laptop. My only real complaint so far is that they didn't make any cuts in the chassis for anything except the battery. So, if you want to upgrade/change out the hard drive, memory or any other component, you have to unscrew the entire bottom cover. If you can live with that and the large screen, it's not bad. The price seems to have gone up a bit since I got mine, but there are bound to be more sales. http://www.buy.com/prod/acer-aspire-as5749z-b964g50mikk-15-6-led-notebook-intel-pentium-b960-2/227013323.html
