If you are asking for 'best' deal, I've had dozens of 'pick it up and you can have it'.
Can't beat free, and most of these were solid pinballs. System 11 games, 90's Bally Williams, etc...
When you are a reputable dealer, established for decades, have the ability to quickly respond to the customer's needs, willing to pay cash, have the equipment and expertise and labor to remove a pinball from someones house with zero damage to the machine or the house... You get deals that nobody else does.
Last week I got a Theatre of Magic back from a customer we sold it to twelve or fifteen years ago. VERY low wear and tear, perfect sides, perfect playfield, a few cracked plastics, batteries dead, but had been moved off of the board. Silver sides, not gold. It came with the agreement that we would also buy the Pole Position video game.
The games were upstairs, and the stairway was (holds fingers apart 1/4 of an inch), THIS close to making the games impossible to remove. It took five guys to manage the turn in the ornate wooden staircase. We got the games out, without any damage.
The customer and I negotiated $5800 for the pair. This is a pretty regular thing for us... buying at about 1/2 of eventual sale price. It all depends upon the customer's needs. If he's happy, and I'm happy, it's a good day.
