If you want free, I like MarketWatch. They have pretty timely coverage of economic releases and give you a pretty good idea of what is going on for the day's session.
If you are looking for a premium service, I am giving Dow Jones Newswires - http://www.dowjonesnews.com a try right now and can report back on how it is. It is a pay service so I don't know if I'll keep it but I have been wanting to see how DJ compares with Reuters (which I already have).
If anyone has any feedback on DJnewswires and whether it is worth the money I'd appreciate it.
