the KP is about $250 to $300 (market price) depending on whether or not it air up and shoot.
the nightmare is in the high 100 and low 200 range also depending on whether or not it air up and shoot.
Not sure about the rest, but they tend to range between 100 and 150 if they air up and shoot. A little bit less if they don't.
If you can make an offer around $400 or so for the lot you'll make some profit.
