I can relate to what Captive_Ball has stated. I recently started to "see the light" when I played an Eight Ball deluxe on a trip out to California 5 or 6 months ago. Most of my experience had been on newer sterns and some of the classic Williams/Bally machines from the 90's. Now I have an EBD LE in my collection and a Fathom on the way. My eight ball deluxe gets more play than any of my other pins at the moment.
I never thought I would see myself paying 4-6k for a 35 year old pin but it is happening. Obviously these prices are for a restored or close to restored quality pin. My thought is that the price is going to continue to rise on these pins as they are becoming tougher and tougher to find.
my 2 cents...
