If you're looking for the best print and scan quality from a budget all-in-one, the Canon Pixma MP210 is the one for you. Other models, however, offer more substantial feature sets.
The Kodak ESP 3 comes with great software for editing photos and applying touch-ups to portraits, but printer software is only as good as the physical results, and the print quality isn't nearly up to current industry standards. Your money would be much better spent on alternative multifunction printers.
The Dell V305w is an inexpensive all-in-one printer that also connects wirelessly to your home network. However, the output quality needs significant improvement, and the cost to maintain the printer is much higher than the industry standard.
The HP Officejet Pro K850 fits a small and very specific niche: offices that need low volumes of high-quality prints -- including wide-format prints. Otherwise, it's too expensive for a general-purpose single-function printer.
