Digital BW, The Print

I've been printing on all sorts of oddball papers with my 2200 so I 
want to create some profiles just for them to create neutral B+W 
prints.   The printer driver color controls don't give me enough 
control because on some papers it's too magenta at some densities and 
too green at others so I can't just raise or lower the magenta values 
(say) across the board.

What's a good, cheap tool for creating custom profiles?  N.B. that I 
am ***NOT*** trying to do color matching across devices, i.e., I'm 
not trying to match my scanner to my monitor to my printer, etc!   
All I want to do is create profiles for specific papers so that a 
grayscale image is neutral at dark gray, medium gray, light gray, etc.

Thanks in advance!
