jump from regular ink printer to ink tank system-worth it?

I have the Canon EOS 30 (not digital!I scan my negatives but never mind)
recently serviced bought NOS 10/2019 and I am printing all my colour
prints on my Canon Pixma MX925. An excellent printer in all aspects
except ink costs. A magenta, cyan, yellow or black ink (XL) costs 17
euros and has only 11 mLs of ink. I searched for a tantamount ink tank
all-in-one photo printer and came with 2 results, unfortunately quite
expensive for my limited budget!The Epson L850 for 400 euros from
www.e-shop.gr and the Epson L6190 for 449 euros from www.plaisio.gr. The
former is with a generous discount and is a real photo all-in one with 7
inks while the latter is the typical office that can print also photos
and is 49 euros cheaper. Plaisio is infamous for its crappy range of
products that are made in China with the badge of Turbo-X. Also it is
infamous for its poor support and bad handling of sensitive items like
hard drives etc.so I'd like to stay away from them.My old printer would
go to my sister who has an ancient laser on an ancient laptop that
hardly runs. So this project will remain a dream unless I can make a
major contract to build a house!Electric-wise (I am an electrician) or
fix 10 washing machines in a week, lol.(I also repair white goods_.I'm
very pleased with my Pixma but I have paid twice its value in ink costs,
not to mention the environmental impact (all the package and
manufacturing and the inks to be shipped from Japan).
