You'd be surprised at the number of items which get re-listed at higher prices. Some people are real rubes. Then there's the guy about six months ago who was flogging his Atari 1040ST -- started at $550, then $475, then $425, then $350, then $225 (IIRC,) then $150 when it finally sold on a best offer.
*sigh* I don't know why, but I feel compelled to get an ST or Falcon. I can't imagine I would actually use it for anything, though.
