Subject: Recycling HP PaintJet color cartridges?

There have been notes posted recently about refilling HP DeskJet cartridges
using a syringe to inject ink into the sponge inside the cartridge.
Has anyone out there tried a similar procedure with HP PaintJet cartridges?
We produce many mostly-blue 8-color FS dithered spectrograms here and
usually end up throwing away a 3-color cartridge after using up the cyan,
with most of the magenta and yellow remaining.  I would like in particular
to find a source of cyan ink that matches HP's as closely as possible.

Also, does anyone know of quality 3rd party alternatives for these
cartridges for less than about $18 each?  Does anyone buy used cartridges
or give trade-in allowances?

Thanks.
