Just a quick tangent...
I've never been a believer in ink cartridge refills, as seeing friends' early experiences kept me away. I was persuaded to try them again due to the high volume of printing I was doing for my business, so I picked up the cheap pack at Costco (IMS-Ink brand) and tried it out.
Believe it or not, these things work darn well. The ink they use is far better than it used to be, and the price savings is huge. I didn't get the "photo color" pack (5 colors plus black) since I don't print a lot of full-color pictures, but I've printed pics using the standard color cartridge (3 colors) and they look just fine for day-to-day stuff.
The manufacturers have made the printers cheap, and recoup their money on the ink. These ink refills really help bring the ink costs down...
