A bit late to this party, but Wall Street Horizon (www.wallstreethorizon.com) has a number of low-latency (< 1000 milliseconds) event feeds for a few grand/month.
For transcripts, there is TR, Factset, Morningstar, and Seeking Alpha (free, but limited). Wall Street Horizon is more of a trading service for quants, algos, and market makers who need the accuracy.
If you are generating Alpha from forward-looking events, Wall Street Horizon (www.wallstreethorizon.com) has the most accurate forecasts and revisions.
