AnotherMike, Ink usage 1800 and 2400
I was just trying to think of another variable in which one to buy. I finally picked the R1800 because I do about .65 landscapes and bright colors, .30 BW, and .05 people. Based on on the relative quality estimates from Anothermike it seemed that the "quality index rating" for me favored R1800 slightly and the cost factor really favored it. I didn't hear any reliability issue differences. Since ink is a big cost factor, I just thought I would check. So I purchased an R1800.
