Also, a version without borders would be nice for historical maps, and a version with less or no text as a base map in general. But I have bookmarked this one, thanks!
The best maps I've found are at http://www.worldatlas.com/aatlas/world.htm
"All maps and graphics created by Graphic Maps, a d/b/a of the Woolwine-Moen Group, unless otherwise noted or linked, and use of same for any application whatsoever (with the exception of outline maps) requires written permission."
From this, I'd say that the outline maps are acceptable, but they don't do oceans.
I could imagine something like this http://www.worldatlas.com/webimage/countrys/europe/euoutl.htm being useful, though.
