I don't know why people get all in a lather about pinball investments all the time. I have yet to see a rich person from the proceeds of pinball sales. If you make extra money on a sale, it is because the title is desirable and hard to get. So be it. You get the money while the buyer gets the goods.
My investment in pinball is the memories that flood back when I play a machine and the highs of achieving play objectives.
BIBLE #56 is mine and stays. I made that choice from day 1 and no money can persuade me otherwise. Money is a commodity, an individual pinball is irreplaceable.
