The Twist is a fun game with a unique moving number feature - the Magic Card. It's also relatively rare. I've only seen one put together.
The only problem with this game is that it was made in a climate where you are required to receive something of value for your coin (more than a light show). As such, this is the -only- bingo that will tell you what your next coin will do. It has a higher than normal odds step for each color, and 10 positions on the magic cards.
It also has an extra ball buyin feature.
It wasn't popular with operators and they likely didn't make/sell that many of them.
I would pick one up, but know that it is not necessarily indicative of other bingo pinball machines (you lose the random award nature).
The gameplay is pure fun, though. The card feature changes the order of the numbers on the card, sometimes duplicating the same number on the card twice! You have to think pretty carefully while playing.
It came with steel, should be standard Bally size legs, which unfortunately I don't know off the top of my head. Will try to measure and get back to you unless someone else can chime in.
