The Wall Street Journal is one of those papers worth buying (though I would stay away from its weekly corproate cousin, Barron's). If you don't mind getting little more than an editorial page (2 pages in the Monday/Tuesday editions), financial tidbits and the more-than-occassional technology story, Investor's Business Daily might also be worth the cash. Britain's Financial Times tends to have a decent view of things from the far side of the Pond. Beyond that, I can't really recommend any national dailies (I wish I could get the Washington Times out of the Beltway).
I do frequently read the WSJ and IBD. Unfortunately I live far enough out in the boons that I can't get home delivery and have to stop on my way to work to pick it up. The aggravation of going to a shopping center, fighting for a parking place, and standing in line to buy the thing is most of what stops me from getting it more often. But as you say it's often worth it.
