I agree Pete.
Pinball machines are like Gold. Ya look at the prices every few years, and they only ever go one way. UP UP UP UP >>>
Its too hard to find replacements, and the replacements never seem to be as good (unless u pay ALOT more.
I say keep em forever ! (Still playing them when ya are 90 yrs old and have to guess where the ball is from ya wheel chair seems the go !) 
Certainly the keepers should always be kept. If that means your entire collection, then "so be it". Either money or space should determine whether a machine stays or goes. We need to carry the torch for the next generation.
