Everyone is out of stock of them because everyone wants them. Just order the unit from bhphoto.com or adorama.com and wait for them to get it. They won't charge your card until they ship it. That is what I did and how I got it a month ago.
I think the rate after rebate is completely underpriced.
They are all made in Japan. It would be a matter of time that only * lens are still to be made there.
I got it last yr before the rebate kicked in . The supply of this batch is probably the last we will see. Somewhat like you should retain the old Sony Japanese made TV. Are they the same? Anyway the value stands
