Tick by tick data

#1
I need real-time tick-by-tick data for NSE F&O market. Can anyone tell me their experiences about their professional data service providers?

Requirements are:

1. Truly real-time data. Delay of fraction of a second
2. All F&O scrips including option chains should be available.
3. Should support real-time download of at least 200-300 tickers at a time. Good bandwidth.
4. Access to data in Excel or with some other DDE type mechanism.
5. Should provide market depth data (5-best bids/best asks)

How do e-signal and quotecenter work as far as above points are considered?

Other than these two if anyone knows some other data provider which gives above mentioned facilities kindly indicate.

Thank you.
