The reflective calibration target looks to be about $70 from xrite.  
I guess I'd need to weigh out the value of an 810 that came with the 
calibration target but out of date vs. just buying a new target.

Interesting suggestion.  The issue I see is that the PrintfixPro 
package is $500.  If I can get a used 810 for around $130 plus $70 
for a new target that's only $200.  But as you say, you're getting a 
lot more with PrintfixPro.

As far as QTR goes can you give an indication of how you use the 
spectrophotometer?  I assume you can use the spectrophotometer 
outside of the PrintfixPro software package?  When doing so are you 
measuring the L values of the gray patches (as opposed to the density 
readings of the densitometer)?
