For colour printing, I found an Epson EcoTank on Gumtree that a local business was giving away for free, having found the process of replacing ink too tedious. For those who don't know, the EcoTank line don't use cartridges in the traditional sense, you just pour ink directly into tanks on the printer. It's a bit of a hassle to fill compared to just putting cartridges in, but for just printing stuff off for around the house, it's worked out so much cheaper for me so far. Plus there's no worry about proprietary cartridges being discontinued in the future. If you can find one for free/cheap, I'd say go for it :)
