Default Good price for used Note 10.1

Hi, I'm thinking about buying a used Note 10.1 tomorrow...I've looked and I think I'm paying a good price, so in you guys opinion what is a good price for a used 16gb wifi model that is in excellent condition (few to no scratches or cosmetic defects) with case?
