This item is hard, scratch that, impossible to find in the US so I ordered from DigitalRev in Hong Kong.
All I can say is WOW !!!!!
I ordered on Thursday AM San Francisco time which essentially was Friday in Hong Kong. My viewfinder was delivered this morning in San Francisco !!!!!!!!
Even better the price including shipping is less than the retail price in the US
$300 plus $19.xx shipping vs. $349 (potentially plus tax and shipping)
They aren't cheaper on all products and I think it is really based off of where the manufacturer prices items but we do have a very viable alternative on hard to find items.
i have no affiliation.
