I actually have found myself liking small flipper EM's better than "standard" ones. Fireball, Kings and Queens (Ball walker kickouts in the middle of the PF is awesome.), King of Diamonds (Roto-target is awesome, as is the layout and rules), Atlantis (Only EM I know of with the 2-targets-down-at-same-time rule, and the bagatelle on the right side).
For multiplayer games, 300 is a good one.. best bonus counter ever.
