You can buy online directly from the largest GPS retailer in Taiwan. I ordered the complete package and had it shiped to my home address in Taiwan (Free 2-day shipping on orders over US$30 within Taiwan, how nice!). The package has the GM270-U, External Antenna and Navigation software for use in Taiwan. The total is only about US$159. My parents will bring them to me next Monday, since they will be visiting me in the US for 3 weeks.
The receiver itself and the antenna only cost US$144 (NT$4990). And on their site they said their international shipping is about US$21.

So 144 + 21 = 165 gets you the Ultra model and the antenna.
The regular model with antenna is about US$113(NT$3890).

By the way, they accept international credit card from any place (visa, master, AMEX, I think).
Good luck! Can't wait to play with it next week.
