I have or had all 3. Sold a BSD 5 years ago and missed it . I got another one 3 years ago and it will never leave. It is simply a top 10 game for me with no other pin like it. I had IM and it was fun for 4 months and then it got old hitting the monger. IM is fun but there are many Sterns as good or better. WCS stayed 3 weeks and it had to go. In my opinion it is one of the worst B/W games ever.
