Where can I can a CD of historical share data for free or the best price?

The only free one I know of is one Bernard Chapman gives away free with Insight Trader charting software. It is also highly accurate and adjusted for all issues, name changes and reconstructions.

You can also buy the data from Dial & Chart (

The thing you have to watch is the adjustments. Some data vendors sell unadjusted data. Others sell adjusted data, but I have some doubts about the accuracy and reliability of the adjustments (I would rather not name them). I have personal knowledge of, and therefore faith in, what you get from Insight Trader.
