I live in Las Veagas, and I have ordered many items from play asia, and I have never had any cost are fees associated with customs. All my express packages have arrived within 1-2 days.
Please keep in mind customs can hold any delivery for any reason at anytime, but I have never had to pay for any international package coming to the US, but it could be delayed if they decide to hold your package for some reason.
No, you do not have to worry about anything. As stated in another topic, I live in Atlanta, Georgia and I received my Caanoo yesterday morning through Fed-Ex as if it were any other online purchase. Plus, Play-Asia has fast shipping as well. My unit came in 2 days.
I see you are worried about customs, just buy it from Play-Asia and you will be satisfied.
