Quoted from RyanClaytor:
Don't do it! Then the middle-pop game prices will skyrocket and the rest of us will have no hope of joining the club!
No worries... there are lots to go around. Spanish Eyes had a high production run over 3000, and Fan-Tas-Tic a few thousand more than that.
Of the 2" versions sharing the same layout (8-Ball/Miss-O/Cue-T) the combined run was around 10,000 units. Even Magic City got up near 3000.
They are still attainable for reasonable prices, so get one while the gettin's good! Middle-pops rock!
In order of preference I'd of course grab any Freedom prototype no matter what condition it may be in. Then...
(tied for second) Fan-Tas-Tic and Spanish Eyes. Fan-Tas-Tic has more going on, but is a bit slower in part due to the roulette wheel. Spanish Eyes has better artwork and blazing gameplay... but is somewhat simplistic.
3. Magic City (very pretty art, less common than the others)
4. 8-Ball/Miss-O/Cue-T (more common, and the same layout as Spanish Eyes but with 2" flippers)
5. Safari (dead bumper is a bit of a bummer compared with the rest)
Beyond those, all that are left are the 1950's middle-pop wood rails. I've listed them a few times on Pinside. Never played any yet and the speed and layouts vary widely... so no idea how well they would compare with the 60's/70's machines above.
I think we need to design more middle-pop games!
