I have Epson printers both at work and at home. I always use originals at work because the one time I bought compatibles everything came out green, but decided to give them one more try for my home printer. Although lots of people swear by compatibles, I'd never get them again. First thing I printed came out very pink. Used the 'clean print head' facility and that improved it, but the colour is still not as good as with the original cartridges. (Bought from Choice as well, but I wouldn't say it was them particularly, I've just never found compatibles to be as good.)
Not help exactly, but at least you're not alone in your problem!
