I've owned pins at home since 2003 and I've grown my collection pretty methodically over the years and have never burned out or gone crazy buying a bunch at once or anything.
My wife and I are thinking about buying a place in the Caribbean in a few years and that sorry of tempts me to sell them, but I know I would miss them.
I still have fun playing and typically play at least a couple of games 4-5 days a week.
