Christine - Know thine enemy - Didn't mean that to sound as harsh as it may have sounded. I'm a student (sounds better than saying a fan which could lead to another misunderstanding) of WW2. The German General Rommel wrote a book on tank warfare. The American General Patton read that book and gave Rommel's army a severe butt-kicking in North Africa. He "knew the book" on his opponent. How he thinks and why he did things the way he did. Sports teams will study video tape to learn "the book" on the other team's quarterback or goalie.
In an auction, any other bidder is an opponent, and "knowledge is power." To know how he thinks and acts, can give you a winning edge.
Having said that.........this is eBay. DON'T OVERPAY......if you wait long enough, a similiar item will be listed by someone else...........
