Digital BW, The Print

Greetings All:

Some of the recent discussions about "eyeballing" prints has raised a 
question in my mind. Assuming a calibrated monitor and the desire to 
match print output to said monitor, exactly how are you folks judging 
your print output?  More to the point, how does one create a 
controlled, comparative evaluation environment, in a 
home/hobbist/student situation, that allows this to happen. Seems to 
be an important, yet not much discussed requirement, especially if one 
is trying to make decisions on value and delicate (warm-cool) color 
tone from screen to print. I suppose some of the pros in the group are 
using expensive, dimable, color correct view instruments like those 
from GTI or MacBeth, but these seem a bit much for the 
home/hobbist/student to use. Can anyone describe a low cost solution 
that works for them.  Thanks
