Tough choice. I am fortunate to have both fully reconditioned and restored. Monster bash and Addams are probably the two most popular pins when I have people over, and reasons why others I know have gotten the pinball bug. I doubt either will leave here. That said if you were to only have one pin Addams is probably the best choice. It is the reason for the revival in the 90's and a testament that it is consistently in the top 10.
