Almost 2 years after purchase, I'm still VERY happy with my Canon PIXMA MG5420 3-in-1 desktop printer/scanner/copier!
One of my main reasons (besides just "price-point") for selecting the Canon PIXMA "MG" series 3-in-1 printer was the fact that it uses a 5 cartridge ink "system". ... I cannot tell you how many times I have had to throw out (and then pay to replace) a "Tri-Color" ink cartridge that had stopped my printer from working entirely, JUST BECAUSE one of the three colors contained within it had run dry. - It's a crummy scheme, UNLESS you are the company (no names mentioned, but I think you all know who I'm talking about) selling the "Tri-Color" ink cartridges.
These Canon cartridges come VERY well sealed from the factory so that their "shelf-life" far exceeds the cartridges from that other (unnamed) manufacturer that actually punches holes in its cartridges' outer-wraps and then just tapes over the cartridge's ink dispensing plenum "reeds". - Ink cartridges that go dry just sitting on the shelf for a couple of months are something I will NOT put up with any more!
AND Finally; these cartridges are PRICED RIGHT even if you don't get the 15% off for being a Best Buy "program" (f.k.a., "RewardZone") member. These cartridges, when purchased as three individual color cartridges, are STILL cheaper (by $10 to $15 or so) than buying a single "Tri-Color" cartridge from that "other" manufacturer.
My ONLY suggestion is: If you print A LOT of documents OR (even more consumptive) A LOT of photographs per month, get the "XL" version of the cartridges. I'm making the non-"XL" cartridges last about 3 to (at most) 6 months, BUT I DO have a separate "stock" document printer for big multi-page print "jobs". - YOUR PARTICULAR LEVELS OF INK CONSUMPTION MAY VARY DEPENDING ON YOUR INDIVIDUAL PATTERNS OF PRINTER USEAGE.
