I know Jeff personally. He's never done me wrong and I wouldn't hesitate using him for a restore.
Knowing the work that Jeff does and based upon the price you paid (shipping included) I think you received a fair deal.
You might disagree but based on current pin prices, rarity, and this kind of condition, obviously you thought so too.

I've had machines restored by Jeff and he does immaculate work and the machines are stunning.
He's always been more than fair to me and I am so picky his work always meets my standards and beyond.
I restore machines and arcades also and I know the amount of work and time that goes into these at this level.
It's a tremendous amount of work and prep and then precision execution and Jeff is an artist.
Usually they are not money makers especially at this price point.

The only failure I see here is the description of the game as "museum restored quality." If that is the case it is up to the buyer to confirm what has been done and verify it before making the purchase, no?
To call Jeff a fraud is harsh, especially when he was willing and still is to work with you. I can understand you calling him a fraud if he made no effort to reconcile any of this.

What struck me most is that the buyer complained after the fact of the price he paid with shipping - $3600, for a game even he described as cosmetically perfect (yet that buyer had no issues paying $400 for repairs).
His description of his game: "when it arrived it looked perfect. Cabinet and head were perfect."

Yet, buyer is publicly slamming the restorer as a fraud and a sham.

Joefoxx22, work it out.

I think more collectors should attempt a higher end restoration of a pinball machine or arcade and see the work, time, and money that goes into it all.
Then maybe they'll appreciate just what it takes.

Also if someone is legitimately willing to rectify the situation why bash him?
