Owning - Having many machines (hoarding?) is great. It means you have HEAPS to do. I could not have many working pins, as I would get bored playing them. So I need to be working on them. Once they work - I tend to lose interest and I want to work on the next machine. There are exceptions - I love my Paragon - that is just the pinnacle of pinball playing. As the years go on, I will have my dream collection in my gamesroom, and also fulfilled the need to work on as many pins as I can get my hands on.
Working is definitely better than playing.
