Well Cube Quest will have to be on the list, and Esh's Aurunmilla, Freedom Fighter, and the Bruce Jenner laserdisc game can command a real price hike, with the limited available original cabinets.
I like the list but I'm in agreement with Hemi on this one and not because I'm making a typical point here, but simply to play devils advocate.
Starwars cockpits do not sell for $3000.00 I haven't seen any. Heck I watched an OP smash one up (minus yoke) once. I would think TESB conversion to Starwars would get more money.
When the economy is on a high and people have disposable incomes for nostalgia then these prices are predictable. Just as when the economy sours, do we get to see the same cabs going dirt cheap.
I think the games that are not emulated will demand a higher price. Just like reproduction furniture you can antique it, put a Chinese mainboard in there with MAME add some talcum and hey presto you have a rare classic game to sell. Just leave the cab in my bedroom for a week and it will be as dusty as an old warehouse.

Hey what a great idea lets make lot of money!!

I think that list needs some revision, and not just personal favourites, but everything on the mhard to find market like Death Race.
