According to Google €130 is about $178 USD. We were recently told that a batch of FB+ were being constructed. They are sold for $100 USD and come with the USB cable. Software is freely available. While the FB+ gets pushed back in favor of the reproduction carts, it is always available.
My suggestion to you is to sell it somewhere other than this forum. Members here are aware of what the FB+ is and how much it sells for. You may have a hard time getting your asking price.
