There was a post sometime this past week about a whole tractor trailer load of one particular model of Janome machines being stolen. It said the FBI has a list of all the serial numbers and is looking for the machines. The notice warned before you buy a too good to be true deal on a particular Janome please check it out. Sorry my brain is fried and I can't figure out how to find the info for you.
Maybe someone else here can check into it before you decide if you will buy it.
Sorry I can't be more helpful
