I have one of the original ones, my friend bought it back in the 80's and I later bought it off of him. I have been offered 700.00 for it and it's got it's share of little dings here and there. The guy that recently offered me the money said they are very difficult to find at any price. I know you think the price was way off on that web site, but if I was offered 700 for mine in it's condition I would say that the other one is in line.
it's not the value of the cue by age, but supply and demand. Back then we were all into Dungeons and Dragons as kids so this cue was the holy grail of cues. We had a lot of jokes surrounding it and we all feared it's presence. Was a lot of fun.
I do see them every once in a blue moon, but be prepared to pay more than you think it's worth if you actually want one. This isn't your typical 400.00 Meucci from the time period.
