Not a huge collection yet, but I'm working on it.
Empire City 1931 (was part of a converted Defender cabinet I got for free, been working on trying to restore it)
Aero Fighters
Gigawing
Vampire Savior
Raiden DX
Ibara
Own a Astro City cabinet and a homemade supergun to play them on.
I also own a Street Fighter II pinball machine made by Gottlieb, great little table.
