I have been following the mining trend in India and as far my calculations go it is not profitable, not sure why you are ordering these miners anyway.
No, I haven't bought any miners in such miners but I hope what you ordered is legit and you get them in working condition.
One suggestion would be to check the "computer hardware" section of this forum where we have many trusted users buying and selling mining and mining related equipment. Rest assured you would not be scammed by the trusted users there but you should use an escrow none the less, although again I lack information as to who does such escrows in this subcontinent. Maybe some of our well known users here would be willing to.
