Digital BW, The Print

I've been doing some digital stuff on my 980 and 2000P, but I'm 
mostly a BW photographer and I have 25 years of film to work with 
(alot of my work was 8" x 10" contact printing- it's tuff to 
approach that kind of tonal quality).  Trying to print BW on the 
2000P is sad- I believe the 2200 is possibly a good choice because 
of the grey ink cartidge.  I've spent alot of time looking at the 
Piezography site, but am thinking the UC 7 color system might work 
(or MIS).  I have a full time day job, but I'm starting to get back 
into photography and need advice on what setup works well for BW.  
I'm seeing used 2200's for $400 and up- I don't feel like commiting 
to a 4000 at this point because digital BW printing is evolving so 
much.  RIP's?  Thanks alot, Kip (714 337-0961, SoCal area).
