People seem to ask $1,700 - $2,500 for T2. The HK ship can be bought new for $50. And that one needs to be replaced because it looks dumb. Slingshot plastics pop up on eBay for between $20-$50 all the time. So you are looking at $100 of purely cosmetic issues that a complete novice could fix. That isn't bad at all.
The inserts don't look worn at all and someone will have to correct me if I am wrong but I see zero playfield wear. Well I am sure it has some in the shooter lane and where the ball drops for the ramps but you know what I mean.
Judging from my own experience in selling games (T2 twice), I do not believe anyone gets $2,500. I would say a good price for both sides would be $1,700 - $1,800. If you can get it for less, then more power to you. The seller may need money and may need it now. People are really weird behind the scenes. I have pinsiders offer me $200-$250 for games listed around $2,000. I see these same people cheerleading for sale threads for games they own.
And of course, if you are in an area where games are hard to find you may have to pay a tad of a premium. And I will tell you one thing, if you pass and someone else gets it for under $2,000 a bunch of people will show up and talk about how good of a deal that was.
I would not be scared off by the ship or plastics.
