A classic Bally - you simply can't go wrong with a MH. Artwork is beautiful on this machine, and it has a "different" sort of theme. From a playability point of view - Bally kept things simply on the game, and I'm convinced they "borrowed" some of "Gottlieb's" playfield design (Spirit of 76 anyone?)
Fantastic machine, and a welcome addition to any collection - and certainly, if it is the only Bally in a collection - it would be a good choice.
