This is a scam as old as time. An old professor of mine did the math, realized buying a new bottom tier printer was cheaper than buying its corresponding refills. Her husband was understandably furious at the stack of pristine printers pilling up in the garage.

While you do save money on ink for larger printers (laser/pro photo inkjet) you are losing a lot of money just to start up. Its also worth noting that liquid ink has a shelf life, drying out, hardening, and a hassle to clean out if not used.

On an interesting note: the EcoTank system is a reversal of the Stylus Pro and SureColor tank system. Instead of slotting in a fresh tank, you're just pouring a bottle into a permanent tank. Good to see Epson taking a practical and consumer friendly approach.
