I laugh at the comments here sometimes. There is just no way that you can buy the machines most of you are talking about at the prices you mention. Like Rusty, I'd buy a Whirlwind and Pinbot for 2700. There is NO way in hell you could get those two games for 2700 bucks, absolutely no way.
Get real people, the prices you think are real are simply not today. Pretty sure the guy wants the pins soon, not 10 years from now.
You can probably find a single game for that kind of money if you're looking for a 'newer' DMD style game, or, a system 11 with an older early 80's game. Maybe something like probably my favorite game, HS2, along with a game maybe like Flash Gordon, and that would be a good deal for 2700 bucks IMO.
