Has anyone ordered any of these "Compatible Inkjet Cartridges" online before? You know, the ones that cost like 6 bucks a tank? Are they any good? Is it worth it to just bite the bullet and buy the name-brand stuff? I'd be printing just text documents so color quality isn't really that essential. Does anyone have any recommendations of a site I could order from? I have zero clues as to which ones are reputable and which ones arent. Thanks alot.
