Go for the "Micromax Canvas Knight 350". It will be available on a few days in Flipkart -> http://www.flipkart.com/...svmtruegma
The price will be around 19-20k.

It is Micromax's flagship phone so it has very highend features. And don't believe in rumors that Micromax phones are cheap and bad. They are of very good quality. Of-course if you buy a cheap phone of 5-6k than it will be bad but if you buy a good quality phone like Canvas or Knight, you will never be dissapointed. All Micromax phone come with 1 year warranty too, so don't worry and go for it.
