Well i would wait for the new models to hit indian shores,currently only the old 2010 NEX3 and NEX5 are sold in india but are within your budget.
The NEX-C3 a 2011 model is a good bargain camera as a newer better sensor with faster AF and if you want built in flash you have to go for the NEX-F3 which is 2012 model may just be over your budget.
The 2011 model NEX5n has touch screen and optional OLED evf and the latest NEX-5R has the phase detect AF+ touch screen+wifi+apps+ live view on any android phone.
