If you're using an HP printer, their ink cartridges are very easy to refill. Since each cartridge has its own print head, it won't clog up the entire printer (unlike Epson). I've been using ink refills from eBay for a while now, they're quality ink if you buy from legitimate ink sellers. They run about $20 for 5 refills (black+color), and plus you can make use of your current ink cartridges rather than throwing them (or even recycling them). But I would only recommend refilling ink to those who are somewhat computer literate. Not that it's difficult to do, but it's not something a lot of people know about, or are too afraid to try.
