I have a CC Jukebox pinball that I like.  It was the last of the E.M.'s in 1976.  I had a Bally Fleet from 1936.  That was one of the first games with a solenoid to propell the ball back up the playfield.  Flippless and surprisingly fun.  As far as modern styles, I like Family Guy or Shrek, same playfield, different props. 
What I would like to own at a reasonable price, would be a Rockola World Series, a Mills Cannon Fire, Gottlieb Amazing Siderman,  Sterns Simpsons Party Pinball or Family Guy.  I would have to sell everything to make room for the new collection,  

  but I'd rather have a variety of different games instead of just pinball.
