Cheap and efficient broker for option trades

#1
I mainly trade in options (and to a smaller extent futures) - on an average I trade aorund 150-200 contracts per month, which would be about 4-5 crores of nominal turnover. Right now, I am paying between 30-40 per contract on Reliance Money. Is there any other broker who can offer substantially lower rates than this. I know RK Global gives it at Rs.9/lot - but clearly based on the threads, there are quite a few problems with the s/w and customer support. And for me, its extremely critical that the s/w and customer support works well.

I think I can signficanly increase my turnover if I am offered lower rates, though obvioulsy I am not not guarantee the same.
