I purchased this about three years ago on Yahoo Flea Market for 6800 yen. I've heard that there are quite a few fakes of the 57BETA, but I don't know the authenticity of this item. It has only been used for home recording, so the main unit is clean. There are no operational problems, and it was recording with good sound. Please note that for those in Hokkaido, Okinawa, and other remote islands, shipping will be at the sender's expense.
