🔹 Wolfgang,....One thing others here might forget,sometimes people need to sell quickly to get money into something urgent.
Or it can be after someone who has died,where relatives sell..Yes there are many reasons for a sale.
Then it will be cheap,..myself have bought a lot of electronics for incredibly small money.
Ask to get the serial number,then it is easy to check if it is okey.
If the seller don't give you the serial number,..then you should be careful.
Maybe even contact the Police.
But take the chance to make a good deal if what I write above is okey,..Then I might even invite him 12 instead of 13 😉.
Ps: Or her,..sorry Huge.!
