Neil-
If you end up with the 8300, printing 8x10 images on 8.5x11 pages laid out on 44" paper is not really an onerous task. I strongly suggest getting a D-Roller (Shades of Paper) to take out the curl. Let the prints harden overnight before decurling. The Lucia EX ink in the 8300 is even more resistant to scuffing, but you'll want to use all precautions, anyway. A good trimmer like a Rotatrim will give excellent results. The final sheets may not be as precise as 8.5x11 sheets out of a box, but they can be darn close. Certainly it's not something I've ever heard anyone complain about.
