I've actually found, in some cases, that the store brand (remanufactured) cartridges can work better than a brand new cartridge.
Check out my thread here.
Going with refilled ink tanks or even refilling them yourself might not be the problem.. the PRINTER might be the problem. As you can see in my thread, my canon won't LET me print with my refilled cartridge right now because it says it's low on ink.

Not for Epson. Have yet to find any that work without clogging the heads and/or give the same print quality.
Other brands have worked well though.......
Epson is notorious for clogged printheads, using Epson ink or not. Been there done that -- will never buy an Epson printer again.
