You asked for the price in Yen, so it was logical to give you a Japanese source.
Your profile doesn't mention that you live in Perth so I wasn't to know. In fact I still don't know if I can help since that could mean Perth, Australia or Perth, Canada.
Assuming it's Perth, Australia (because it's larger and because of the way you use English),
Minidisc.com.au has it for $535.00AUD but that's just an online store not an electronics retailer, sorry.
:crystalball :crystalball
hey, we don't seem to have a "crystalball" smiley.
lol sorry about that, just having some fun and trying to be helpful :)
Edit Forgot the conversion to Yen, courtesy of
xe.com - $535AUD is Y41,170.33. Ouch, doesn't look good value compared to the Japanese source.
