[sdiy] ebay internal shill bidding?

I do the same as Paul, with the addition of a low-money "courtesy bid"
at the beginning of the auction, just to throw my proverbial hat into
the ring.  I then wait until the absolute last possible nanosecond
before placing my real bid.  I feel like if I bid when there's more
than 3-5 seconds remaining, I'm taking an extravagant risk.
