cis-continuous ink systems for r-1900

yooperdooper

I have an Epsom R 1900 printer.To save money I am considering installing a cis.I noticed there is a wide range of prices on the cis systems and some are easier to install than others.I print about 20 or more 11x14" prints per month.Would such a system be worth it for me? thank you

20 or more per day, yes, maybe.

20 per month, no way for me.
