Porhabs a little late to answer but i give my experience.
I have a Canon Pixma 3000.
I don't know where all of you are living.But if you want to try alternative ink and you live in a country where Carrefour supermarkets are, give those a chance.
I've tried the one from Pelikan and some other as alternatives and the best ones (imho) are those from carrefour brand itselfs.But you must live somewhere in a country where Carrefour is availlable offcourse.
I have never jused refills (don't like needles :-))
