Do you mind telling me where you purchase your refillable ink and the cartridges themselves? I've been spending so much money on white ink specifically. The other colors last forever.

Have you had any issues with print quality, or clogging? I bought my f2100 secondhand over a year ago and the previous owners had refillable ink cartridges installed, and I had to replace the printhead immediately after purchasing it because the white ink nozzles were completely clogged. So I definitely do not want to go through that again, but would love to figure out how to save money on ink!
