It is much better to buy brands of repute when one spends anything above 12-15k. it is upsetting to see guys sell bikes assuming we cyclists will not know whether the brands are from germany or timbuctoo!
There are some good brands currently available in the market , Trek, Schwinn Merida , Scott, Bergamont . If you are in Pune go visit nachiket at Lifecycle. A better place to invest your money in Pune than most bicycle shops
