I looked at the Z3100 before buying a iPF 8100, then the 8300 and now my 8400. The Z3100 looked ok except glaringly deficient chroma in dark reds, i.e., dark reds were devoid of color, in comparison to either the iPF 8100 or the Epson 9800 (which I owned), for that matter. It got better with the 3200, I hear, but don't know how it compares with otter brands. While the 8100 was also weak in the dark reds, although better than the HP, that improved significantly with the 8300, to the point where it wasn't a problem for me. The Z3100 is also a lot slower than the Canon printers and has awkward roll loading from the back.
