Cheapest way to transfer money from Taiwan to US?

My wife (who is Taiwanese) is taking a low interest government student loan from a bank in Taiwan (Chinatrust), which we need to use to pay a school in the USA.

What’s the least expensive way to get the money from Chinatrust to her University?

I’m wondering if a Taiwan Paypal - USA Paypal e-check would work? (Paypal e-check is a $5 fee)
I can’t imagine wire transfers would be less expensive than that.
What about travelers cheques?

Any suggestions or comments greatly welcomed.

Travellers checks for sure, though technically illegal. Just make sure someone on the other end is receiving them and cashing them before paying to your school, and don’t leave them blank! You can get them at Chinatrust or any other bank.
