Quoted from CactusJack:Ever hear of Ebay?
ebay.com link
Most of the games sold for less than $200 or $300 are either missing parts, or the tower does not work. There was a huge lawsuit against (was it Mattel?) the manufacturer because they just outright stole it from the designer, so very few were actually sold
I remember seeing a kickstarter for a revival of the game, which is pretty great
