I'm looking into the best source of news out there, but I'm at a loss as to what to go for. I am specifically looking for a source that announces mergers & acquisitions.

My current experience:

- RSS feeds: good, solid way of getting (free!) dedicated info you can manually sort as you please. The con is that there can be a delay of up to 5-10 minutes and that's critical.

- Bloomberg Terminal: I haven't looked too much into this, but the cost is prohibitively high. Still, is it a good source?

- Paid news sites: Hard to tell. The ones I saw didn't have a trial period so I couldn't try them out.

What do the experts here have to say?
