Which Laptop to Buy ?

I am looking to buy a laptop. I like the dell and Sony brand .But SONY laptop is costly when compared to Dell laptop. LenovoLENOVO laptop is also an option.But i am not sure about the quality of LENOVO laptop.When i compared the prices on Dell India with Dell US.There is a huge difference between costs.I can carry a laptop easily from US.Now you suggest me which way to go.But carrying laptops from US has a disadvantage that i will not get thier warranty in India.I need to buy urgently..Tell me what to do ?
