Pinside got thousands of members. What percentage of those members do you believe that owns more than one pin or even a single pin?

Sure there are people that can afford very expensive and large collections but I don't think that this is more than 10-20% of the pinsiders.

I am in sales business as a Product Manager at the moment, married with two kids, and I can afford, maybe, one pin per year.
What I can afford however are many (nice deal) projects. Because searching, picking and restoring is the whole deal of being in the pinball hobby.

So, in my opinion, don't try to buy Willy Wonka or Strangers Things or what ever just yet , instead try to find a Gorgal project, or a Fathom project, or any project. Be creative on restoration and at the end of the day you will own pins very cheap and most importantly you will be able to experience the hobby in it's full scale.
