I considered telling you just to google it, but I did it anyway. There are tons of options, but many of them have Intel i-3 processors and 11" screens. Ideally, you want a computer with an i5 and 8GB of ram. Anything lower than that is an ipad/tablet aka worthless.
This is at the top of your price range, but its pretty solid (i5, 8gb, 14")

You can see what you're working with here, you can spend like 200-400 if you get an i3 with 4gb of ram and 11" screen, but its not really a computer anymore IMO.
