I've heard of people using MIS or MediaStreet (Image Specialists) inks
who are photographers and happy with the 3rd party ink. The tanks
aren't so hard to fill if you use the method of breaching them in a
small spot in the bottom chamber and using a short blunt needle with a
rubber seal and then pull air into the syringe and then let go and let
the vacuum pull ink in. Rinse, repeat. The thin heat-sealed "plastic
wrap" is hard to make a ink-tight closing seal with, but the main body
plastic works with the usual plugs or glues. Stratitec offers seals
that fit the smaller of the holes covered by the thin heat-sealed
"plastic wrap":rubber plug: 16 reusable Extra Large Plugs

For that way, use two syringes (one in the outlet port) and a way to
seal the
other syringe to the smaller of the fill holes (cut away plastic) so
you can push ink into
the cartridge and have the air blow through it and out into the outlet
port syringe (with no plunger).
Clog-Busting Plastic Needle

caulk and a washer or grommet to make a flexible seal around a short
blunt needle.
As a general tip for hot glue sealing of anything, it can help flatten
&
smooth the hot glue if you get a piece of smooth flat metal and spray a
little silicone
Lube or oil on it so it won't stick.
