I know that sometimes that they over do the price a bit. One of my friends is a HUGE Beatles fan and I was telling him about the show were they had the "Butcher Baby" cover on one of The Beatles albums being worth $500 (not played, etc). Since he goes to alot of records shows and looks online for Beatles stuff. He was saying that he has seen the same album in the same condition go for at most $80/100. I realize they are saying it is auction price, but still.
I do still like watching the show for the historic value of the what peopel are bringing in.
