Here's the long list ;

I'd stop at 1984.

It really depends on your budget and your preferred manufacturer. Availability of the title also needs to be considered.

Bally

Fathom
Medusa
Flash Gordon
Eight Ball Deluxe

Williams

Jungle Lord
Black Knight

Gottlieb

Rocky
Black Hole
Haunted House

Stern

Big Game
Galaxy
Nineball


Really - If you LOVE Drop targets, you cannot go past Stern Meteor - But that was 1979. Paragon would be the other game I'd suggest.
