I have a Epson Stylus Photo R1800 that I specifically bought to make large prints of my photos. I need to replace the cartridges but want to get the cheapest price I can. I also want original Epson cartridges since they have the archival quality inks.

I only use this printer for the high quality prints, I use a Stylus Scan 2500 for normal printing in which I refill the cartridges. Generics would be OK, as long as they are archival and I would want to see the data on them.

Any suggestions?
