depends on the games, in terms of value the big one is mine storm 2, most of the library is pretty good though from a play perspective, or if there are any extra accessories, 2nd controllers are super expensive (like ~100 dollar range for a good one) , a light pen is pricey, but you can make your own, and the 3d imager is insanely expensive (and awesome) odds are though it would be worth it if you want to own a vectrex, you'd be hard pressed to get a better deal on ebay (plus shipping is awful with them)
