Quoted from darthripley:What do you all think is a fair price to offer?
Mr Pinball Price guide is $1800 (not that it's the exact price). I've seen them go in the $1600-2000 range. One just sold on ebay for $3800.

It's over priced IMHO. You can see if he will come down on the price but likely he will ignore you if he thinks it is worth that much. My friend actually just picked one up locally for $500. It was a lucky find. If I would have saw it I would have nabbed it too.
