I used to buy only the authentic cartridges but the last time I bought re-manufactured on ebay because I did not want to put out $50.00 or more since mostly what I print are patterns and recipes. I was hesitant but I don't have an expensive, top of the line printer so figured they were worth a try. They loaded and work just fine. I think I paid around $11.00 or so for two, one black and one color. I will order from this guy again and keep my fingers crossed that I have a similar experience. (I use an HP Photosmart D5069 printer.)
