A $10k price tag for a game restored by HEP is about the norm, even though it's higher than the typical price range for that title. That's just because of the amount of work and new parts/materials that go into it to make it look as new/mint as possible.

I would suggest that you look at some of the restoration threads posted by High_End_Pins to get an idea of what is done to a game that he restores. It is well beyond a typical shop job or teardown that most people do.

It's not about the specific person per say, but the work that has been done to it.

Like I said, it's way beyond a typical refurbishment. I highly suggest taking a look at HEP's restoration threads to see what is actually done to games. Brand new cabinets with new stencils/decals, full playfield restoration or replacement with clear coating, all metal parts polished to a mirror finish, and much more.
