Canon PG-50 High Capacity Fine Black Ink Cartridge for the Pixma Series Inkjet Printers and JX200 Inkjet Fax Machine Review:
Fair deal also!
The CL41 and PG40 are smaller cartridge size than the CL51 and PG50. I did not know this until I read about this in Adorama. Very nice to get this kind of information when shopping for things, like inc cartridges. Price is good also. Thanks Adorama!
