I don't think the search for good pins is ever over. I thought I had every pin I wanted and while at Expo I went to Terry's house (pinballlife.com) and he had a flintstones machine. I had no interest in that machine at all until I played it. What a blast. Now it's on my list of "buy it if you find one cheap." I think the goal has to be to play every pin ever made and you may find some gems you had no idea you would like.
Ditto - I played Wotto's Flintstones and thought it was a blast. Very underrated pinball. I would look at buying one if the price is right.
