I wanna share with you my experience buying a HE device.
First of all, better use a courier service instead of postal service (it's much more reliable). I personally received my device by UPS. The delivery cost is $50 + $7 for some transit tax.
After receive it, you should pay a VAT at the custom office. For me that was $30.
In other words it cost me $110 + $87 to have my own HE.
