RJ - I too am with you. I tried on the SDDS in Tokyo last year and it just didn't appeal to me in the least.

In the short term you may be correct about the values of the older 16600. BUT, could the SDDS be another Cosmograph? Recall that back in the 60's, dealers just about couldn't give Cosmographs away....nobody liked them, and they were sold in small numbers....and we all know what happened with Cosmograph values....
