Just checked Ebay.. they don't go for a whole lot, boxed.. I guess they're just waiting for an absolute moron to come along, or they are completely unaware of what they sell for. I could see them pricing it at $250 and allow someone to negotiate (way) down, but I see something like this and won't deal with the person and I figure they're shady.
I found an original Odyssey system in the box at a local church flea market
in late 1997 for $20. I tried to haggle that down but the lady wouldn't budge.
It was complete and in mint condition. I sold it on Ebay for $206.
I found a lot of classic stuff at flea markets that year (Emerson Arcadia 2001 for $40)
and made a lot of money on Ebay. I am sorry that I sold that system though. I have
3 O^2 systems buried somewhere (back from my Amok and Multicart days) and
along with 5 Vectrex systems that doubt I'll ever part with.
