Two things that make me prefer the Canons over the Epsons: "Single Ink" technology - even with the six-color photo printers, there are separate ink tanks for EACH color. Saves a fortune on ink. Then, print heads. Canon uses semi-permanent heads that are easily taken out for cleaning (or letting them soak on a wet towel should they ever clog up). Epson uses Piezo technology permanent heads that cost more than a new printer to replace.
