PSLV is undoubtedly among the cheapest launch vehicles (the cost includes that of PSLV-XL variant, other variants are even cheaper). The launch contracts are usually negotiated according to price per kg of payload to the orbit. Given that the estimated value of the space industry today is around ~$200 billion, ISRO should charge higher price for foreign country satellites it launches through its subsidiary Antrix. ISRO is the jewel in the crown for India and congratulations to all those wonderful scientists who are making India proud.
