I've been refilling cartridges for a couple of years now and need to buy a new kit. I use an HP5550. Can anyone recommend the best kit supplier? The kit I will be replacing is made by Startitec and the colors were slightly different from HP colors. FYI I can usually get 4 to 6 refills on the blacks but haven't been as lucky (2 to 3) on the color.
