Buyee isnt the only game in town. There are many handlers.
The biggest hurdle is the shipping cost. There is no way to get an accurate shipping cost before you purchase. Since you have no idea what the dimensions of the box will be.
Buyee clearly packaged all 3 turntables for international shipping. They made their own box and used expanding foam to form fit the TT, which was wrapped up in bubble wrap.
What they didnt do was prepare the TTs properly. They did not secure the platter, remove tone arm weights. or isolate the dust cover from the TT.
They seller of the Y7 did proper prep and secured the platter and tone arm. But buyee did all the rest.
This the Y7 I bought:

Even with sipping it was far less than Unisound. Its also in way better condition than most of the JVCs I have seen on thier page.
My advice would be to use a payment service like PayPay for buyer protection, and be patient. Then look at all the pictures very closely. Most of the electronics that pop up on Japanese auction sites have come from long term storage. Its clearly evident in the photos. Lots of dust and corrosion.
Be patient. Eventually one will pop up from a personal collection. Like the beautiful Denon I posted earlier.
FYI, the term Junk just means used in Japan. Generally its just old and not taken care of but still functional.
