If you have the money to burn, the Canon Pixma MP960 is a great choice for photo hobbyists who need fast prints and great print quality. We prefer this model to its comparably priced competition.
The HP Photosmart C6280 lacks many of the features that make a photo all-in-one compelling, and its print quality disappoints. Your money is better spent on a different all-in-one.
Its features set is oddly unbalanced, and better all-in-one inkjet options cost just a bit more, but the HP Photosmart C5280 is a good bet for casual home users on a tight budget.
The HP Photosmart C6180 all-in-one tries to be everything to everyone, and ultimately it fails to meet this lofty goal. It's a good printer at a decent price, however, for the home user who wants to consolidate all tasks into one machine.
