I use a non-EcoTank Epson, but I have added on a 3rd party Continuous Ink System. It consists of four ink tanks outside of the printer (which you refill with 3rd party ink, cheap), with surgical tubing running to fake ink tanks inside the printer. The fake ink tanks have a little chip with a sneaky-beaky reset button on it, which scrambles the serial number of the ink tanks. This works so well, and is so cheap that I don't take into account ink costs anymore. Cheaper than my laser per page, but I can print out art and sell it.
