John,
For that kind of shipping cost, it's not worth it. Considering the speakers are made next door in China, I don't know why Hsu hasn't set up a distributor in India and gotten their inventory from across the border.
Of the other options you listed, my choice would be Kef speakers. Any of their Q series, which has the tweeter in the middle of the woofer, give terrific soundstage and imaging. Their bookshelf speakers don't have as much bass as the Hsu bookshelves, but that won't be a problem since you've got that part covered with subwoofers.
