I recall one buyer, greatbikemoves, who always ended up paying enormous prices for vintage stuff - probably because of shill bidders. I was always amazed to see some of the closing prices when he was involved with the bidding; I passed on every one of those auctions because of my suspicions.

However, my main reason for enjoying seeing the bidders was that I connected with a few enthusiasts that way - before I found out there was an easier avenue: forums.

I always get there in the end, but sometimes it seems I end up taking the most circuitous route!
