Quoted from KCPinhead:I guess my first pre-requisite is overall quality of the game. Would love something like in the top 35 of the rankings on this site.
Realistically, you are looking at getting a stern pro or a 90s bally/williams.
It will really depend on what you are into. JP, DP, IM, ST, TWD, and MET are the forerunners for Stern. I think JP is the winner of the bunch, but it would be difficult to find if it is truly a "hard cap" budget of 4500.
Most of the bally/williams games are either above your budget or fall just outside your ideal of getting something in the top 35. The shadow, funhouse, fish tales, the getaway, judge dread, BSD, or whirlwind are all options.
I will be very direct with you...I think the game you are REALLY seeking is The Shadow. It is one of the best values out there, and has been for a longggg time. It is a top 10 pin that's hurt by a somewhat cheesy movie and alec Baldwin's mug on the translite (which most people change out to an alternate anyway). If the theme was the matrix, Harry potter, the goonies, jaws, or something of the like...there's no way it's not in the top 10.
The only other option I might suggest is to split your budget and opt to get 2 pins for each half of that $4500 cap. This brings up a lot more choices, but it may actually be better in the long run.
