I don't understand your issues with shipping. The cost per unit is $USD 59 which includes shipping from India to anywhere.
For that price you can expect to get your BITX40 in about two weeks.
If you opt for the additional $US10 for DHL shipping you are potentially opening up a big can of worms.
You will get the package in a week but many folks from various countries (including USA) have found that they have had to pay additional charges to DHL
for brokerage fees as well as duties and/or taxes, which could add up to as much as another $20 or $30. Not worth, it to shave a week off of shipping.
So $US59 will get you a BITX40 in a couple of weeks.
