At the moment, the HP Compaq Presario V3155 is a great deal for it's price, I got the laptop last month after a long research, and I am very content with it's performance, you can play some good games, like GTA:San Andreas etc... and It will do all office work with much ease, it's an AMD based laptop, great value for money. around 35k in market.
But you should mention the budget for any meaningful suggestions.
