Digital BW, The Print

I am considering buying the r220 . I have read here(Clayton and Roark) about how great its is 
with MIS inks. How good is the color with the Epson inks? I already own the 2200 and the 
HP7960. I like the QTR and BO on the 2200 with Ebony, and the b&w on the 7960 is nice, but 
I'm looking for a new toy, I guess. Can anyone comment on using the r220 for both color and 
b&w, please. Or am I just replicating what I already have? How does the r220 compare to the 
2200 in print image quality?
Thanks,
antara
