Sean65: It's now got to the stage that it is cheaper to buy a new printer than to replace ink cartridges when they run out. Never seen such a rip off market in my life. Ink is more expensive than gold.
I have them both, and the Epson 7900 has always been just slightly better than the Canon 6400 in terms of resolution, much better with paper handling and loading with its straight through path, while the Canon has been a clog-proof workhorse. If the early reviews show Canon has finally addressed some of the paper loading issues and it is better than the 6400 in resolution, I'll buy it in a heartbeat.
