Letsbuy has actually put up the xperia play for 20k as opposed to the 32k quoted in flipkart. But if I were you, I would wait for reviews before buying an xperia.
Galaxy SII sure will be priced 30k upwards at least at launch. LG optimus black might be 25-30k but looking at the reviews I do not think it is better than any of the current flagships of HTC and Sammy albeit the better processor.
Amongst the available, since the SAMOLED galaxy S is out, you might want to try out the HTC DHD if you can live with the somewhat dodgy battery life and the gigantic size.
@pauldmps- The Neo has the best specs in its range. Name a phone which has better specs and priced lower than the Neo? Bravia screen,Exmor R, latest version of Gigernbread. You must be kidding me. The term overpriced is based on a comparison of two mobiles of similar specifications and the price between them. Neo has the best specs in the zone.
Nexus doesn't have a micro sd slot, currently sgs or sl without a shadow of doubt else sgs ii or other dual cores within 30 k also incredible s is good too
