I bought the NES setup back around Y1990 and I've still got i; cost $200 and I know for a fact that the joystick adder was another $40. What's the fuss these days, Duckhunt or Mario?
And once you figure out the tricks, you'll consistently blow through Mario and win with speed and ease, and then.......the fun is over.
Edit: OP, if those people in your area are selling for $200+ what they bought for $59.99, that's not being a lowlife scalper, thats called being an entrepreneur and making a profit, and of the best kind of profit, tax free profit!!!!!
