As an example...I have a Gottlieb Big Hurt (Baseball theme) for sale in the marketplace - 2850/obo.
It's a 1990s DMD game for under $3k with a packed playfield, 3 flippers and lots of shots.
Other than that...I used to have Jokerz and liked that game a lot too (Poker theme with upper playfield). Probably in the $2k price range.
Good luck to you!
