Digital BW, The Print

guys I need help.  I am looking to get a epson 2200 and turn it into a 
black/white only printer.  I have been looking at quadtone ink sets 
from lyson(dye), mediastreet, cone, and inksupply.  I narrow my 
options down to cone and mis.  I need some real facts not just 
personal bias for one brand vs another.  I am leaning toward cone 
beacuse in the latest ink its just black ink and you can buy paper for 
whatever tone you want(warm,cool).  Mis is great because the mixed ink 
together can give you up to 40 differnt tones.  I am also looking into 
offering this solution as a printing service to the local photgraphy 
community in my state(did research and there is a need for it).  If 
you guys can help me that would be great. Thanks.
