Another Vote for Indiabulls, negotiate, you would get 3 paisa intraday each side deal easily.
1).Powerindiabulls software is the best of trading platforms one can get, atleast of many i came accross.
2).No Annual Maintenance charge of Demat a/c.(one time A/c opening fee is Rs.900/-)
3). No recurring charge of software. (one time fee is Rs.750/-) however you can also trade without it, using the browser.
4).you can place orders on phone.
5).No hidden charges in last 3 yrs i've been using them.
Don't get stuck at any company which has poor customer support, a paisa or two extra hardly matters.
