I use Epson also.
However, I use off brand printer cartridges bought from printpal or 123inkjets. I like buying a box of 5 cartridges of each of the 5 colors for $65 rather than paying $45 a cartridge.
Epson ink is fantastic and does last substanially longer. However, I find if I'm printing something I want to last it is a high quality photo and I have it printed at Mpix.
Scrapbook pages that get printed go in a plastic sleeve in a photo album and seem to be holding up well after 10 years.
Having said that...I tend not to print my pages now. I save a second copy as *.tiff in a screensaver folder and use that folder as my screen saver.
I hate how if one of the 5 cartridges is empty you can't print. I also hate how you have to remember to go back and go into advance settings to set the print to black and white only each time you send a job to the printer. The darling confirmation screen for my weekly unemployment is blue or cyan ink and I forget to change it so that cartridge is almost empty.
