Unfortunately i haven't many option to choose! Mango is imported in Greece and according to one colleague who had try one in Kenya, as he cut it from the tree, the mangos which we buy in super market are several levels lower in taste and aroma! May if one day visit India i'll try your favourite variety
Anything that is imported will have additional tax burden and that must be the reason, the affordable ones might not be the best quality. I am sure, if you come to India in summer ( June), you will find so many varieties.
