I've just purchased a Jet Tec remanufactured cartridge for £8 - it works fine. I took out the old cartridge for a look inside - the top just popped off to reveal a sponge. I dug out some black fountain pen ink - soaked the sponge and put the top back on. Out of curiosity, I put the old cartridge back into the printer and printed out a page of text. To my surprise it produced a print out as good as the remanufactured cartridge. I only wanted to print out one letter and an envelope - and would have been quite happy with the Quink powered cartridge. Now I know what to do - I'll save a few quid when the remanufactured cartridge runs out.
