Quoted from oropuro:How big is the collection, if you have more than 3 pins I would go SC if fewer I would go DH,

Safecracker is a bit of a novelty game with shrunken playfield and cabinet.
Dirty Harry has a great layout and is fun to play.
Although 6K for a nice Safecracker is a good deal and you could re-sale easier down the road.
Really Apples and Oranges when it comes to gameplay, I would recommend playing five games on both titles and see what one grabs you more. Both are good games.
I have always wanted a Safecracker to put in my bedroom because it is so small-I could shove it in a corner. My wife says hell no-that aint happening-lol
