Not really as the SG made receivers are not really rare. There are two different times SG made receivers for Inland. But they are not rare as they made many thousands of them. The first SG receivers were marked SI and those are considered to be rare. Then there are the receivers that SG over ran their contract with. Inland had to put an X on the end of the serial number as it was a duplicate number and those would be on the rare side too. All of the receivers SG made they put the serial numbers on them for Inland.
