Wildlife lens for d7200

They've been on the second hand market for about the price of a Sigma 150-600mm Sport over here

Over here they seem to be around 1.5 times the price of a new 150-600 Sport.
I have also seen somewhere trying to sell a new 500 f4.5 for only a few hundred dollars less than the new f4 Sport.
