If the LCA is up and running in the next few years, perhaps BD would consider buying a sqaud or two. Who knows? it would certainly be cheap, and given how India is desperate to make its mark in the defense sector I'm sure it'll come with many guarantees. We gave Ecuador a pretty good deal.
I do not represent my govt, but I think BD airforce will not opt for any military hardware or avionics from India. If we are not in a military pact with India to jointly fight against China or Burma, then we are not supposed to make such a purchase from India.
Also, note that even in today's age neighbouring countries are perceived as potential enemies by the military doctrines. How can a country make military hardware purchasing from such a country!
