Did you see the Pinside Ad that gets tacked on to the bottom of the thread?... I know they rotate, but for me it offered a PZ in North Carolina for $2300. I'm guessing the one you are considering is a lot closer to you, but the ad has plenty of pictures for comparison purposes.
BTW, my PZ and the resets when playing it were the impetus for creating my WPC Power Fix Daughterboard a few years ago.
