I have TWD Pre, and a nicely modded Tron Pro. I think I have a pretty sweet collection overall... but if I had only one pin, it would be my Metallica Premium. Like Pezpunk, I don't even like the band. This machine is the spirit of pinball to me. Fast, fun, bright, a bit edgy... Borg, Lyman, Dirty Donny are a holy trinity as far as I'm concerned.
Borg is the man.
