Quoted from Shapeshifter:

Demand has softened in what was already a very niche area.
Shame really as some of the 50's Gottliebs are fantastic players. Sure they don't play like JP and the like but they are a huge challenge.
Was only a few years ago that 1950 Glamor went for $15000 on ebay so there are some exceptions.
And Glamor is not a great player!

Quoted from smohr:

I like my Double Action. I always play 2 players. I have it set for the "Double" match and when that happened... what a sound, bam bam bam bam bam bam… games rack up. Only happened once so far. And the gobble hole, most times it's a PITA but when the time is right and sink the ball, it's usually enough to rack up a game or two.

You are kidding right? It's been explained in this thread like 3 times.
Modern pins don't equate. In my totally unscientific estimation if you own one pinball machine made after 1992, chances of you owning one EM is less than 10%. Chances of you owning a woodrail.... probably like 1 or 2%. I wish this was not true but it's just the way things are with modern pinball owners and trends.
