I have an iP4300 (which I think was the forerunner of the iP4500) and I wouldn't be without it FOR COLOUR PRINTING - the quality is great, especially for photos
Mind you, I'd also stick to Canon inks and papers - the combination of the three does seem unbeatable
Shop around for consumables though as the cartridges are NOT cheap, and won't last so long if you do all your printing in "colour"
I also have a Laserjet 6p for the majority of my printing - how often do you REALLY need colour after all?
