Compound Microscope recommendation

You are going to need to try these for yourself and your application. For example: If you will be mostly using 50 X to 100 X , you don't need an oil immersion lens. For inexpensive scopes I liked Unitron . But a quick look on the net shows some things have changed since I used them ; Also, my experience was inverted stage/metallurgy. I recommend a binocular. A good light is essential. Don't get more magnification than you need ; a fuzzy 1000X is not as useful as a sharp 100X . I have no clue about the India market or prices, But Nikon , Canons and Olympus were excellent . Many other excellent names like Zeiss , Reichert and Wilde. A used brand name is better than a new unknown maker , in my opinion . Today I expect a video display is very common ,however I am not familiar with them. You will need to look on the net or in a library and learn about things like "exit pupil". Good luck.
