My latest GnR to look at turns out to be a sited machine. Considering it's currently on site, I don't have much faith it will be any better than the one I inspected yesterday.
You never know. You might find a machine that requires a little elbow grease, but turns out to be a gem. Just depends on what price they're asking. Again, you may have a way of getting it cheaper if it is sited. Good luck with your quest for a Gunners. I still think it's one of the best pinball machines I've played.
Cheers!
