go with Global Datafeeds. their data is pretty accurate with minimal lag. backfill is good too. customer support is excellent.
They get their data directly from the Dotex feed (data-vending service of NSE).
I have tried nearly all the data providers...
I would advise you to stay away from the likes of manshiRT, MDP etc that source their data from dubious channels...all of them have delay and sometimes inaccurate data as well.
only drawback of global data is that their price is a bit high and they don't have cash and MCX data.
nothing beats eSignal though.
