Digital BW, The Print

It's certainly worth checking out.  I have the Datacolor print spectro, 
and I've made color profiles with it, and generally I've been pleased.  
However, I recently started reading patches for making QTR curves, and I 
noticed that the spectro gives very inconsistent readings of the same 
patch.  Right after calibrating, the first measurement is way off.  
After a few measurements it gets more precise, but it still varies way 
more than any of my densitometers.  With color profiles, it's possible 
that the huge number of patches helps out with this, but with reading 21 
step strips, it's quite annoying, and not very confidence inspiring.
