In the Portland, OR area, the average asking prices are:

2WD
1st gen or earlier  --  $1000-1500
2nd gen                     $1500-2000
3rd gen                      $2000-3500

4WD
1st gen                      $1500-2000
2nd gen                     $2000-3000
3rd gen                      $2500-5000

And these are mainly stock form.  If they are asking less, then they are beat.  I wish I wasn't broke, I'd get some killer deals.  And right now there are some early 2wd ones that are in good condition that have some serious potential.

And the average 3rd gen 3.0 4Runner goes for $1500 all day long.
