highly appreciateive of your response...
well, heres what i've learned for the moment---i called the aduana (customs) here, and they told me that when the package comes, i'll receive a notice to go to the aduana to pick it up and pay any applicable taxes...HOWEVER, if i have a tourist visa (which i do), and present my passport which proves as such, and the laptop is mine, then there would be no taxes at all. we all know that there are no straight answers here, but i'm hoping this pans out. i'm also using the US express mail.
thanks again you all are very helpful.
