It would be a excellent if the poll was broken into 2 x parts.

1. how many fully working pins do u have, and

2. maybe a second question about how many non working project machines.

The reason I say that, is some people have 5 working machines, and a dozen projects stored somewhere which havent been touched for years, and perhaps a few years before they will see daylight. or a whack working, and only a small percentage as projects. etc

The working pinballs, gives a better feel for what is working and out there today flying the flag for people (new or old to the hobby) to play.
Just a thought. Prhaps the vote could be split to show real figures ?  

(mine would be all working today for example, with a project arriving soon)
