I really like the game but the parts are expensive so you need to know what you are getting into.
Neon topper $80 (not held in place by cover)
Partical separator ramp $115
Cliffy for antigravity $36
Flipper coils $15 each
Flipper rebuild kit $40
It is supposed to have a painted back glass, it might be a hard sell with a paper or translite replacement. A really nice example is worth $900 to $1200.
