In the budget u mentioned, HP COMPAQ laptops will be best suited for u.
My suggestion is go for HP-COMPAQ CQ45-206AU
Config: 2 GHz AMD Turon X2 ZM 80 (1 MB L2 cache)
2 GB DDR2 800 MHZ ram upgradable upto 8 GB
250 GB SATA 5400 rpm HDD
DVD wirter
Wifi, CARD Reader, Blue tooth, 1000Mbps lan, Fingerprint Reader
14.1" screen with 1280x800 Max resolution
ATI Radeon 3200 Onboard graphics with HDMI output
After buying this u can increase the RAM by 2 GB (Total 4 GB) by spending just Rs1400 to Rs1600.
