I can't speak for the longer-term reliability, but we have an Epson Ecotank which you literally fill with ink from a bottle (no cartridges). It was more expensive than other Inkjet printers (since they don't sell them at a loss and profit from cartridges), but ours has been humming along for two or three years. We got an extra set of CMYK bottles, but we haven't had to refill it yet (fairly large reservoirs).
