I decided to pay the extra $5 - $10 bucks for international shipping. Cost me $79 total to have it shipped to my door from the U.K. and took 1 week exactly for me to receive it. I went with the 3540 because NEC seems to have better "aftermarket" firmware support, (Ex. - Liggy & Dee, T.D.B., etc.), and it supports DVD-R DL, whereas the 1640 does not, (not sure if I will ever use DVD-R DL, but having the option is nice).
