Quoted from Gatecrasher:Anyone who says they wouldn't take ANY pinball machine in nice shape for free isn't a real pinball enthusiast.
That's not necessarily true...if you only have x amount of space and your current lineup takes up x-1 amount of space...you don't want to fill that last remaining space up with some pin you aren't crazy about. Most people are saving that last space for a pin they really want...not just any ole' free pin.
