Just bought a £38 ‘all-in-one’ Epson Wifi printer from Argos, currently on half price. Cartridges are about £8-10 for black and individual colours (plus 10% off if you buy extra’s with the printer. Wifi is good as the printer can live in the spare bedroom whilst I print stuff from the comfort of the sofa 🙂
Kodak does have cheap ink but I think the colour cartridges are combined, so if you print out lots of one colour (blue skies or perhaps a logo on letters, you have to stump up the cash for all the colours at once) when its only the cyan you’ve run out of. Also the printers are more expensive.
Not sure how up to date this is, but apparently Lexmark and HP have the print heads integrated into the cartridges, which is the reason they are the most expensive, but also means the printers are not so ‘throw-away’. Most printers, you cannot replace the print heads.
