I got my Optima this past May. It was $375 shipped to Ohio. They shipped it via UPS Worldwide Express. It took about 3 days from Hong Kong.
Basically, 300 bones for the radio and 75 clams for shipping. It comes with an invoice stating it cost $50, a customs and duty avoidance measure.
The Optima was fully converted and I suppose, tuned to factory specs.
I guess they could ship it by a cheaper means, but unsure how it would affect transit times and customs.
Yes, the radio plays well, but I still walk with a slight pucker having spent so much. I really don't think it's truly worth that much.
Others will disagree...
