The pricing I've been given from i3system does not include any taxes, custom's fees or duties as this would vary country to country.
For example, in Australia it would cost a further 10% in GST on top of both the goods and shipment price, plus custom's fees of approximately $100. So the TE-Q1 @ $499 USD with an accessories kit and shipping comes in around $1000 AUD after exchange rates, GST and custom's fees are taken into account.
I've noticed on this forum of people referring to a TE-Q1 30Hz version, but when I asked i3system they stated they don't do a 30Hz version of the Q1. Does anyone here actually have a 30Hz version of the Q1? If so, are you able to share where you purchased it, as this is something I've potentially interested in buying.
