I had a Hyperball a few years back. That and a Rapid Fire. The Rapid Fire was such a bad seller for Bally they ended up turning the remainder cabinets into Centaurs and EBD Deluxes.
They're fun to play for a short time but you get tired of them very quick. If you have people over to play they'll get played as they do have a novelty attraction but if you're wanting one for strictly your own playing I woudn't recommend it.
