Cheapest 1 minute historical data sources?


I am getting started with Quant trading, and I would like to know what are the cheapest and most reliable data sources in India?

I would like to have 10 year historical 1-minute tick data for at least Nifty 50 stocks.

I used Zerodha PI, and its good that Zeordha let’s us download 60 days of data for free.

If anyone is still looking: some gentleman has posted updated 1 minute prices from 1st Jan 2017 till 23rd March 2020, for 200+ securities on Kaggle for free !!
