I bought mine at the Car Toys store at Amazon and had it sent to
www.shipito.com (I can highly recommend them, have used them for several items). The total, including overseas shipment, was only 447.50. Even though I missed the $40 off window (because I was waiting for Irex's confirmation on the feature upgrade) I am not complaining,
Shipito charges no commission, they make a little on the shipping. But I find it very reasonable and service has been very good.
