Thats why I said, slect 3-4 models and then I can help. Personally me and Ash both use same LG model, i.e LG P500 but its available for ~10K only.
For me all android phones are same except the hardware. that's I am saying select few and then we can decide.
You can take decide those models based on screen size, camera, processor, RAM etc and above all your budget.
I tested a Huawei Model IDEOS X5 for 13.8K few days back which was good too. But as i said, you should decide 3-5 models first.
