i recently bought a Samsung automatic (WA82V4G) 6.2 kgs for 11500/- with installation in delhi. So far happy with it though its been less than a month. it has good reviews and personally i feel its decent enough for bachelor/small family usage.
there is an another alternative of this same model with lesser capacity..no idea about its model number, but considering the fact that you will use it in hostel room it might be a good option( smaller size).
