What is a good place to acquire cheap/free historical quarterly filings data for US Companies? Specifically, I'm interested in the consolidated financial statements. The data should be well-structured and machine-readable (csv,tsv,json, etc.)
I'm familiar with CompuStat and CRSP but both are well out of my price range. Coverage need not be exhaustive, but most of the Russell 3000 (with dead companies) for the last 5-10 years would be great.
