Given the fact that I own almost all the machines I've ever wanted, you would think I would be content ?

Haunted House, Spirit, Medusa, Fathom, KISS, Paragon, Viking, Flash Gordon, Flight2000, Spirit of 76, Mariner,  A-Go-Go and Circus Voltaire.

Nope !
Still want - Embryon, Hot Doggin', Star Race, Circus, Solar Fire, Winner, Planets, Super Score.. .. ..

I want to start restoring Woodrails - and I'd love a Jigsaw or Mermaid

The chase never ends - I guess the day I stop chasing, I may lose the "fun" of collecting and restoring.

I have the "all time must have pinball" = Paragon. Never to leave the collection. Ever.
