Is anyone familiar with these units.  There are a number of them being offered on Ebay and 
they look like they were OEM units packaged with a Zerox product.

I have a Spectro that went bad and I'm waiting for its replacement but I have no idea how 
long that will be.  I'm looking at the ebay unit as a temp replacement for a densitometer to 
finish some QTR profiles.  My concern is what kind of software is needed to make those 
units work as a Densitometer.  Will I have to buy hundreds of bucks worth of software to get 
anything out of those units, or will the Driver Disc have enough to provide some sort of 
Densitometer output?  Sorry but I have no familiarity with the X-rite line and the seller 
doesn't appear to either from his disclaimers.
