I wouldn't believe the ebay stats @ those prices. Something tells me they are just downright made up by the seller or have been manipulated somehow.
No one in the universe is that stupid the pay those prices for something worth $10 originally.
I bought a few spares after my first one from a different seller and $10 turned into $24.
They are sitting amongst all my pinball crap somewhere.
I saw something similar recently at Toyworld for under $20.
I am sure another ebay seller must have something very similar for very low numbers $ given more than one Chineese company would make them ?
