Just depends on who wants one, I suppose. Last time I looked at the auction sites they were going for 25 and less, since they are old technology now. If its still working properly, its a fine receiver for analog satellite signals, the problem is, most of the satellite transmissions are now digital. The box can still be used to control a big dish actuator, moving dish around and controlling polarity of the lnb on the dish. Like the old post above said, the shipping can be steep since they are heavy. I have a 550 and a 650 still using them to move my dishes, nice receivers for their time.
