Digital BW, The Print

Has anyone tried the R220 as a black-only printer using Clayton's R200
settings? If so, did you find it necessary to make any adjustments to the
settings Clayton uses for the R200? Apparently there are some differences in
the drivers (according to Paul & Clayton).

AND has anyone used the R220 for BOTH black-only and with MIS/Eboni inks as
recommended by Paul R.? If so, how did the two approaches compare?

I'm considering whether to buy a second R220 and do some comparing of
prints. If Epson does give a $50 rebate I can have two printers for $90.00
including shipping, but the offer expires today (at least the offer I found
on the B&H website). That's about what I pay for a set of inks.
