Are ink-tank (EcoTank/MegaTank) printers cheaper to run than cartridge inkjets?

Across the reviewers we read, the consensus is yes for anyone printing regularly: refillable supertank models ship with one to three years of ink and dramatically lower cost-per-page, which high-trust expert coverage repeatedly calls the main reason to buy one. The trade-off is a higher upfront price and the requirement to print often enough to keep the print heads from clogging.
