The 123,000 Yen new, was a price I saw a seller in Japan saying that's what the new price was but I can't confirm
it's right as that is $1,528. Australian dollars, looks like an over inflated price to me ,I've seen the UM-T12 listed second hand it Japan for a little over $500 Australian dollars but also seen them listed in Japan for a $100 Australian dollars.
