Digital BW, The Print

I've been wondering if anyone one has successfully calibrated a flat 
panel monitor for working with their digital output?

Saw the link for Colorblind Prove-It at Inkjetmall and notice it 
works with CRT and Flat Panel...any pitfalls to be aware of before 
purchasing an FP?

Thanks,
Cleavis - beginning some research.
