Digital BW, The Print

As I don't own the proper equipment, I've decided to seek out profiles 
for money.  So far I've run across Cathy Stratton and Eileen and 
Mark's Custom profiles.

I notice that they use rather different targets.  The one using the 
target with more squares claims that helps them get a more accurate 
read.  Any thoughts?

So, if any of you have used either of these (or another source), 
please comment on your experiences.

BTW, these both charge $40/profile.
