Most warranty covered defects or issues usually pop up in the early usage of the items so if it's a working unit I agree the chances are not good for problems unless it turns out to be something special down the road that should be covered by a manufacturers recall. As for the price , I agree with others , that's not a screaming deal. I picked one up with 2 years warranty for < $1500 with the WM10 , printed manual and waterproof headphones. I know three users who bought their units with the extra coil for < $1900.
Dealers need to make money , private sellers just want it back.
