[time-nuts] Thunderbolt GPSDO

Shill bidding is putting false bids (from friends etc) on to drive the price
up when you are selling. 

Putting a large first bid is sometimes done from someone going away for the
duration of the auction and putting on the highest amount he wants to pay in
an attempt to secure the deal in his absence. Have done this myself when
going on holiday and no internet access.

However, I normally lurk until the last 15 seconds of the auction before
bidding (good reason for having accurate time on the PC!!)

A) $250 is a heckuva good deal on a Thunderbolt, if that's what it is.  If
they end up going for less than that, I'll buy a couple just to squirrel

B) The seller determines the opening bid price.  In this case, it was $250.
Not cool to accuse people of criminal behavior when you don't understand the
basic auction model.
