Go to eBay and look under completed listings for real-world values. In general each unit looks to be worth somewhere between $500 and $600. If they are in perfect condition functionally and physically then the values could/would be higher. Original packaging and boxes also adds value.
Ebay can give you an idea ,but .Condition, has it been cleaned in and out ? Then there are people who think its Gold....Has it been tested and played all the inputs and out puts working properly....
