The higher end models are almost always on sale for not much more then the super low end models. The MP610 can be had for $140 or less online. 

The MP610 is much better then the super low model.

Sound like lackluster follow-ups to their predecessors. Passable machines, but unimpressive. The comparable Epson models produce a lot more bang for the buck. I still haven't forgiven Canon for dropping the individual cartridges from their lower-end models like these. They pioneer the system then forget about it.
