Hi Sean,
Well, Exterminator would need to correct me if I am wrong, but I don't think that Halx (or Hali etc) is available to purchase at the moment, regardless of your location.
If you only want to use it with VoxCommando anyway, I would recommend getting the USB-UIRT which is made in the US, and is less expensive than either the Halx or the iTach. Just google it. The main thing to remember with the USB-UIRT is that you must operate it via a computer (awake).
