Depends what type of game you want, easy, hard, one for all the family etc....
In my opinion the best game around that coin is Whitewater, although you will prob not get a top condition one for that money, but maybe one with some minor playfield wear, and/or a few cabinet dings - neither of these will affect the game play. This is a top game that everyone seems to enjoy, including new people who have never seen a machine, but it is also pretty difficult to get the big jackpots etc.
Next on my list would be The Shadow, this is a hard game which is what i really enjoy - it has a fantastic final mode, awesome music and extremely underrated in my opinion - a lot of people whinge about the backglass, but backglasses don't really matter too much to me.
Other possibilities that i really have enjoyed are Roadshow (good humour and challenging, but kids are drawn to it as well) Jurassic Park (ball eating T Rex - great stuff!) both these have shaker motors as well.
Another really good title is Black Rose, not a lot of people seem to talk about it, but its another game that almost everyone that plays mine really enjoys.
