A little background.... I've ruined two good Epson photo printers with crappy ink refills. About five or six years ago I swore I'd never buy cheap replacement ink again. But after printing more and more, I just could not put up with the costs and waste of factory cartridges. This time I set out to purchase quality replacement ink that was more affordable, instead of buying the cheapest available. Through lots of reading, I found Precision Colors of NY (http://precisioncolors.com/). I bought their 6-ink refill starter set for the same price as a set of new Epson cartridges but with 10x more ink. As worried as I was about the quality, I'm very happy to say the results are 100% as good as factory ink. Great product, great price. I'll try to remember to post back. If anything negative happens, I'll report back for sure, but for now, I can print for less than $0.10 per 4x6.
