Digital BW, The Print

Hi All,
Is there anyone using Quad inks that uses a densitometer to 
calibrate their system? If you do could you please let us know what 
model densitometer you might use? I am using a windows XP system and 
are considering the purchase of a X- rite densitometer. 
I think that it would be a acurate way to set up the monitor and to 
check the dot gain on my 3000.
Any comments?
