4. Atari 5200 game console
Original price in 1982: $270 (price in today’s dollars: $619)
Just sold on eBay for: $78.50
Atari’s follow up to the classic 2600 console, never really took off. I had the 2600 (which I loved) but how bad could the 5200 be if you could play classic games like Defender, Frogger and Centpede on it?
Then again, you could also play Gremlins on it, so maybe I'll stick with the 2600.
