I don't think the 5 year backtest this site does really tells you very much though.

Indeed.
I would never put any money into a scheme based on ETF backtesting;
other than perhaps SPY, there aren't any ETFs with histories plausibly long enough.

Hypothetically speaking, it would be great if someone were to put together
a downloadable file from public sources that included returns for
the "usual suspects" ETFs backfilled to a much earlier date with the most
appropriate index data. Daily is a lot to ask, but some of this isn't
very hard to find on a monthly total return basis.
e.g. I downloaded monthly REITs data from end 1971 from NAREIT, and I
have daily total return data from 1989 for almost any country or region
you could name that I got from S&P simply via a free registration.
Pinnacle offers CRB continuously-linked futures index from 1971
(as well as separate energy, grains, industrials, meats, metals),
though unfortunately that's not freely available.

Anyone feeling up to pulling together a data set of whatever's available for free?

Jim
