The Fluke is a professional grade 5.5 digit DMM with regular and four wire measurement capabilities.  It saw me through a K2/100 build, a KX1 build, and many other projects.  It is is very nice shape and fully operational.  Its last full calibration was in November of 2005 lapsing in 2006.  I haven't seen the need for a formal recalibration, as it comares accurately to my other dmms and standards.  It comes complete with power cord, a good set of test leads, and the original manual (user and service).
 
You can scan the internet to get the complete specifications on the 8842A, which is the top of the 8000 line.  However, there are a few reasons why I like it.  1) it is a very solidly built, reliable unit; 2) it has a low noise front end and uses thin film resistor networks (first in this series to do so); 3) the controls are straight forward and logical; 4) measurements are held; and 5) it has a bright electrofluorescent display.  It uses Fluke's true rms technology.
 
The last two points really add to usability.  You can't always be looking at the DMM when you are looking into the work and placing the leads.  Here, it will hold the reading after you remove the leads.  You can zero it by touching the leads together or just take another reading.  The electrofluorescent display is much, much easier to read than LCD displays (you can read an ef display across the room in full light) and easier on the eyes than the a red led display.
 
As of this morning (April 19) the least expensive 8842A on eBay is being sold for $299, "buy it now".  It does not come with a manual, but Tucker (a well known test equipment vendor) is selling the manual on eBay separately for $50.  There are other 8842As on eBay, admittedly with the GPIB* option, that are being offered for as high as $499.  I am asking $195 plus actual shipping for the dmm, probes, cord and manual.

*The GPIB option is not very useful unless you are doing automated testing and mass production.
