the best laptop that is worth every buck is LENOVO
in Our society people buy what others have regardless of there needs so you will never hear about this company. they actually bought the laptop wing of IBM.
i am using there machine and am really satisfied with it it will cost you 45000 for a new one with
500 gb hdd , i5 sandy bridge ,4 gb ram ddr3 , 15.6 led , 4-6 usb ports and 6 cell battery
it wll satisfy your beginner to intermediate level needs
hp and dell cost more for the same specs (dell inspiron = 56500) some times even more.
and another imp thing ASK FOR LOCAL WARRANTY avoid dedicated memory laptops they consume more battery and you will not need the extra memory.

here are some websites for further consideration

the prices on the websites are more than the market (1000 to 1500)
