To anyone who might be thinking about refilling their ink cartridges, I just have to say, "It's really easy." My tri-color cartridge (HP#57>35 U$D a pop) was running low and I had bought a small refill kit from Mr. Inkjet (thanks NooNoo) and so I refilled it over the weekend. The prints look just as good as before and so far haven't experienced any fouling of the print heads. It was a little messy, but a hot water and isopropyl alcohol mix cleaned it up quite well including the syringes. My next project will be to mod the cartridge and remove the sponges and I will post again when I get to that point. My only reservation is that, living here in the US, it should only be a matter of time before this practice is outlawed too.
