Never heard it played out myself, it's always been a tape / CD swappers record to me. I got mine going on for 20 odd years back - must dig it out again though!
Auctions eh, you never know what the outcome will be, it's been said lots of times before, you just need a couple of people who stick way over the top bids on something to make sure they get something and up it goes!
Maybe that's what happened here?
Let's see what the other one on there goes for, I know there's at least 1 more currently for sale....
