I'm in Ecuador, so bitmaintech listed my S1 as a "Video Game Gateway" and around $160, so Aduana (Customs) here inspected it, didn't know what it was, so they only put a $16 duty on it. DHL paid it for me and then charged me $10 for the courtesy. So in all, I only paid $26 for duty/fee and was thrilled it didn't get hung up for a month.

I ordered a 1000W power supply from Tiger Direct for about $120 plus about $45 in shipping, and not only did customs hold it up for about a month in Guayaquil, I had to pay $100 tax on the damn thing. Customs... what a racket!
