When I was a dealer in the 70s and 80s the Orion was a joke, prices MUCH lower than street prices. Dealers [not me] would keep it under the counter so they could offer low trade ins. But try to get THEM to sell you a used component for the listed price. Maybe its gotten better, but then it was strictly a tool to fleece the customer. Used prices have always varied wildly, even in the same store; and local markets are quite different in which things sell best.
