Well I really don't like spending insane money on printer ink, I think HP and everyone else offer their printers so cheap that they they offer make money with ink. I've used some of the company's refillable inks and while the ink is fine, they can't create a software chip or code that OEMs have in a printer to negate the refill ink.
