Total is $203 delivered to door.
To avoid customs / vat, just ask them to mark it as $20 value. I did it many times, it works fine for small packages.
So anyone can get it new from factory for €170.
I'd prefer to get it from factory instead for such little price difference. Probably the same for most buyer here.
Good luck for your sale
