payment systems

Internet money transfer systems, along with the costs for sending $100 from US to India.

• paypal.com - does not work in India :(
• ikobo.com $4
• remit2india.com $3 cf
• westernunion.com $15
• wire transfer from your bank to their bank; although this is a minor pain to setup each time (can not be done over the web) and there is a fee

I hate setting up extra accounts, and am trying to decide which system to use based on (a) trustworthy provider (b) whether I would use them for other purposes long term and (c) fees.

Do you know other ways to send money from US to India? If so, please let me know.
