The 3800 is awesome (I've had one a few weeks). Can't comment on the papers. I'm a Premium Luster man. The canned profiles with the Epson papers are really great if that's an incentives to stick with their stuff.
Compared to the Canon iPF5000 ?
Yeah, yeah, I know. Epson gave you the show printer so that you'd make posts like this.
But hey, you're amongst friends. So spill the beans.
