Hello,
What you'll need to look for are any with Intel i5 processor, 4gb RAM should do and since you're playing not heavy (not requiring too much) games, you'll need some average graphics card. I'd help you with link, but I never bought anything over Internet, so that's the best I can do. Laptop which I described up there can get around 300$, or at least in my country would (South Europe).
Regards.
