Gardner, MA
Quoted from KingDaddy:I'll take two x $1k Earthshakers, one $1.5k Funhouse and a $2.5k TAF.
I bought a 2.5 taf a couple weeks ago 
Never paid more than $1100 for any of the 3-4 Earthshakers I've owned.
A lot of the Gottlieb System 80/A games are pretty awesome and worth a look, many can be found for $1000 and under. (NOT 80 B!, don't really care for them and HATE the cabinets)
As mentioned before, a TON of the early Bally SS pins can be found, hell you could get two for a grand easy. They're easy to work on, lots of aftermarket parts, excellent build quality, easy to break down for transporting- the list goes on, plus they're tons of fun because they're hard to play.
