A fair price would be $200 for the lot.
You could probably sell it for $250 - $300 on eBay.
Worth and what you could sell it for are seldom the same. Realistically, a 15-20 year old console that isn't that rare and likely to fail/need repair at some point in the near future should only be worth around $30. But alas, collectors and people looking for a nostalgia hit will pay the same initial retail price for a 20 year old piece of hardware, sometimes a lot more (like those poor Neo Geo collectors - Don't worry, I'm one of them).
