I have owned three Canon printers now, and all have been excellent. I prefer to use the own-brand ink tanks (which I do for the 1st year to comply with guarantee requirements) but I have found that generic ones work very well, and give extremely good results. However, the latest printer (iP4850) was too new for generic cartridges with chips to be available, so I have shopped around for genuine products. Amazon has unfailingly come up with very good deals, so I shall continue to use genuine cartridges.
