That's a great price, but be warned... the Atari 10-in-1 is not that great. I LOVE the Pac and Ms. Pac JAKKS games, but the Atari si very disappointing. A few games seem slow, and just simply are emulated poorly.
I guess it would be worth $5, but I'd put that cash towards one of their Pac or Ms. Pac games if you actually want to get some play time out of the thing.
