Digital BW, The Print

I've been thinking about moving to MIS variable quadtone (still have 
to use up some color ink I have). I'm somewhat strapped for 
counter/desk space; therefore, I've been thinking the bulk inks with 
refill kit would probably be the best route to go. However, if the 
CFS is significantly less expensive and or easier to work with I may 
just make the effort to make the space for it. Any suggestions?
