I just thought I would report on my experience, as I have received many
good tips from these groups.
I have had very good experience with getting supplies from tylermartin
(
www.tylermartin.com ).
So far I have used replacement cartridges for my Canon i450. They were
less than $2 for the black.
I just used their black refill for an HP PSC 1600. It was the easiest
refill I have ever done since the ink comes in a plastic squeezable
bottle that has a nozzle already in it.
It was $5 and is good for 2 refills.
The quality seems to be just fine.
The shipping is $6 no matter what the quantity, and they have been
fast!
I have no affliation with this company
