Traders' Roundtable

I am looking to purchase historical end of day price data on futures going back to the early 1970's. I have found one company at www.price-data.com that sells data on a CD for a reasonable price.

Does anyone know of any other companies that sell end of day data on Futures?

Thanks

These strategies might include long term trend following systems, short term trading systems, and contra trend following systems, all within their portfolio to hopefully improve their risk adjusted returns ...
