go for LG Optimus One.
LG optimus one mayn't have best look, best colour density or a good camera but what it have is all round features & good build quality. for day to day use without a huge emphasis on photography, its a good one to be considered.
also if looks matter, nothing beats SE Xperia X8. but sadly that its only strength i can list out.
Dude LG Optimus One costs 11.7k. I got mine at that price 4 days ago. It's seriously without doubt the best phone even in 15k price range, please consider it. It doesn't look shabby btw it's pretty ok.
forget LG Optimus. other than looks it got nothing to show off, similar to SE Xpera X8.
below 13k, no Android based HTC (used mobiles only avl). theres only 2 good choice: LG O1 & Samsung G3. if you can pay 12k its LG O1 or if you want save 1k & ok with low resolution screen & Eclair (Android 2.1) for now, Samsung G3.
you can't go wrong with any of these 2 mobiles.
