I had similar specification two months ago..and i ended up with N78..not a touch screen but good phone. A touch screen for 12k works a bit tinny. But if u r okay with a LG phone cookie is quite nice..just check for its price in India; I think its beyond your budget.
If you are desperate for a touch screen, i recommend to increase ur budget. And if you can't, then go for Moto rokr E6..best phone at 12k.
