You're behind the times dakota. I saw a 2 wheel drive 4450 with 1850hrs sell at auction earlier this winter that brought $34000. It was in NW Iowa. Used iron is hot hot hot. Although this one was cherry.
That does seem a little cheap. I would be interested to know where I can find power that cheap. Average condition 4440s have been selling for over $21-23,000 in NE SD since around 2001.
