I want to put ONE bid in and be done with it.  As 
long as the other bidders have placed their max 
bids, then all is fair and good.  If I bid too 
early, I end up with people who keep rationalizing 
their own bids higher and higher.  Feh.

But I honestly can't complain about people who put 
lots of little bids in (which you can clearly see 
when the auction ends, by looking at the bid 
history).  That's the way a "real" auction works, 
which is what Ebay originally set out to do.  
Everybody creeps their individual bids up by the 
smallest amount until all but one person gives up.
