that is very interesting. as you guys have been saying, it's the right price for the japanese-made one... the american-made ones are more like twice that price.
I guess you could chance it and if it turned out to be MIJ, send it back (no risk- it's their mistake so they shouldn't even be able to hit you for postage!)... not sure if i'd be willing to take that risk though.
EDIT: the '52 one is twice the price on the same site... and i can't find the '62 one on dv247... actually, scratch that, it's £1100.
