I made a pretty detailed post on my TAF restoration when I did it a few years back. When I finished it, I figured it was worth about $3000 less than I had in it. Now that player's condition ones are reaching 5 figures, what's mine worth? I never really planned to sell it (unless they did a remake), but everything has a price....
The main issues I could see a buyer having are:
Restored HSA original playfield instead of a new repro. I had a couple CPR golds, and the clearcoat on the restoration blew them away. You can tell it's been touched up in a few places since the paint is slightly higher than the original artwork. Still beautiful though.
Replacement boards instead of originals. They've worked flawlessly and I'd prefer the reliability of new over 30 year old boards, but some people would want originals.
No color DMD. Don't really care for them myself, but some people expect them in a high end restoration.
