I was using www.moneycontrol.com and found it to suit most of my needs. The rediff portfolio manager is also good in terms of user interface, clean and simple. Recently came across this - www.stockz.io which is in private beta now. It is amazing and much better than Yahoo, Google finance or moneycontrol and all others. The limitation is that it only has BSE prices and no NSE prices. Also it is in closed private beta now. I have 7 invites left so pm me if you need an invite.
Thanks!
