The more time and effort put into these games, the better the final outcome will be. Being a hobbyist, time is totally irrelevant. It is all about "fun" for me. I've always enjoyed the journey from the forgotten and neglected pinball to the final working game.
The game was sold a while ago, and the only time I hear from the owner is -"Have you got another one ready... ?".
"Working" on these pins is not "work"..it is a pastime. ;)
