Oh wow. Thats a lot of good games.
IMO, Johnny Mnemonic will probably pad out your collection the most since you already have stop & go games in your collection (STTNG & TZ). You don't currently have a pure "flow game". The cabinet fade is extremely common. A shame they decided to use that red color scheme, as it does games no favors (fade also on No Fear).
Cirqus Voltaire is another great pin on your list, and one I would think of adding if I were you. Replacing plastics shouldn't be too expensive. Make sure to check to see if the sound board is working properly.
Guns n Roses is a great pin. The topper is usually missing on most of them out there. No surprise really.
Shadow cabinets aren't always the best in shape. Usually some kind of fade going on. The good news is the head decals are reprod, so you can replace them if they are starting to peel or are ripped. Shadow rings and mongol characters are much harder to replace. Thank god I got an extra ring for my machine, if one goes bad.
I would pass on the TOTAN if its as bad of a shape for the price. Will take quite a bit of work and money to get it looking good, if its as bad as you listed. I don't think a game title is enough, if the game is a real expensive fixer-upper. I have turned down an AFM I could have owned, because of this.
Ditto passing on Safecracker & Haunted House, as most of the games on that list are better.
