i don't get why people on this forum always assume shill bidding? What passes as shill bidding is how i bid when i buy stuff on ebay...it may seem silly but i prefer to do it that way.
Psychologically it discourages me from spending too much because i see the price increasing gradually, whilst just clicking once to put in a max bid wouldn't seem so real to me...so i would put in more then regret it later.
