I have an R2400 that I run with MIS k4 inks.  I do this because I like 
to print both color and BW.  If you're going to only print BW, then you 
should probably check out the UT-3d inks.  So far I'm pretty happy with 
both bw and color prints.  I print mainly on EPSG and on Crane's Silver 
Rag.  I use a color-managed workflow for color and bw iccs with ABW for 
black and white.  Recently, Paul recommended replacing the yellow 
cartridge (I think) with a MIS carbon ink to get more lightfastness.  
I'll probably give that a try soon.
