Hi Guys ,
What do you think is the best way to transfer money to the US . I have investigated some scenarios but the rates keep coming up pretty bad and with the amount of money involved for MBA ( > 70K $ ) , this is going to be a huge hit

...
1. Travellers cheque ( apprehensive about this method ).
2. Western union ( very expensive charges ).
3. NRE accounts ( not really sure how this works ??? )
4 ......
5.......
If you have options please fill up the above blanks.
