Before the ip4600 i had the ip4500 which worked great with jettec ink cartridges which i thin k are the best third party ink. But the boffins at Canon made the ip4600 with different cartridges and the results from jettec are not very good. Thats why i've been reluctant to buy ink flow systems because of the third party ink.
Anyone using the Canon ix6650? At £160 it look very good value for a a3 printer. Uses the same printhead and inks as the small ip4950 i imagine. I've always liked Canons.
